Those of us in the Mac rumor and news business (is there a difference?) love it when we get a good tip, especially when that tip is from someone who has given us good, solid info in the past. iLounge featured a post last night called "Ten New Details on the Apple Tablet" that passed along some rumors that they've received from one of those solid sources.

While I won't parrot back the bullet list of ten details that are in the iLounge post, here's the gist of the article: Apple has created at least three prototypes of what editor-in-chief Jeremy Horwitz calls the iPad. The prototype that is still in the running has a 10.7" diagonal display, runs iPhone OS, and looks like a large iPhone 3G.

The device will have two variations, one with 3G networking built-in (think of it as an über-iPhone 3GS) and another without it (a mongo iPod touch). The larger display is expected to have about 7 times the surface area of the iPhone, and about 6 times the resolution, allowing easy reading of books, magazines, and cropped newspapers.

With the extra screen space, the new devices are designed to bring ebook functionality to the iPhone platform as well as make a more compelling platform for games, media, app, and the web. Apple doesn't expect this device to compete with netbooks, hence their continued denial that the company will come out with a netbook killer. Instead, this will be an extension of the iPhone platform.

Horwitz finishes his list by noting that the device is still awaiting a green light from Steve Jobs, and that it has about an 80% chance of making it to market. If it's given the go-ahead, the source is stating that the device would be announced on or before January 19, 2010 and would go on sale in May or June.

While this is still a rumor, the information is from the same source that gave iLounge the scoop on the iPod nano 5G, the iPhone 3GS, and the Chinese iPhone 3G. It appears we'll still have to wait until 2010 before the fabled tablet appears in our local Apple Stores.

The legendary Dev-Team has done it again. It just released the new version of the Pwnage Tool, a desktop application that's used to create custom firmware packages to jailbreak iPhones and iPod touches.

Jailbreaking is the act of modifying the official firmware in order to run applications not approved by Apple. Chief among those applications, at least for the iPhone crowd, is the SIM unlock that allows the phone to be used on unofficial cell phone service providers.

The Dev-Team has found holes in previous versions of the iPhone OS that allow this code modification and has developed tools to make exploitation easier for the average user to accomplish. Once implemented, the jailbreak process installs an app that acts an unofficial App Store of sorts. The iPhone or iPod touch user can browse and install games, utilities, themes, and general applications. Cydia, one of these installer apps, even has a store with applications for sale.

Traditionally, when Apple releases a new iPhone OS version, that software upgrade breaks any jailbreak and SIM unlock present on the device. And so, you end up with the cat-and-mouse game that Steve Jobs alluded to shortly after the first firmware loophole was exploited and the original iPhone was unlocked.

Well, the mouse has stolen the cheese once again, and the Pwnage Tool released today will jailbreak the latest firmware, version 3.1.*

The big asterisk at the end of that previous sentence is that the Tool will only work on about half of the devices that use the iPhone OS -- only the original iPhone, original iPod touch, and iPhone 3G. The iPod touch line just released, as well as the 2nd generation iPod touch and the iPhone 3GS, cannot be jailbroken at this time. That means if you've already upgraded to 3.1 on your 3GS, you still won't be able to SIM unlock it as of the time of this post.

So, if you want to SIM unlock your iPhone 3G or the original model, Pwnage Tool 3.1 should do the trick. On the 3G, you'll need to use Icy or Cydia to also install the ultrasn0w app that actually performs the software unlock; however the original iPhone should be unlocked without this additional step.

You will need a Mac to run Pwnage Tool 3.1, but a Windows version is expected in the near future. Also expected soon is redsn0w, for both Mac and Windows, that further simplifies the jailbreak process by avoiding the need to create a custom firmware package.

Keep in mind, if you've been waiting for a jailbreak solution before upgrading to the latest firmware, many users have had fairly substantial issues with iPhone 3.1. My fellow TUAW blogger, Josh Carr, has reported that lots of iPhones and iPod touches are working poorly after upgrading. You may wish to hold off and stick with 3.0 or 3.0.1 until a solution is found, either by Apple or some other group of smart people.

But, if you're so inclined, you may find links to download Pwnage Tool 3.1 on the Dev-Team's official blog. Make sure to read the instructions thoroughly, and take heed of all of the warnings. They are there for a reason.

I was chatting with my TUAW colleagues this morning about Mac versus iPhone programming. And as per usual with these conversations, we veered in the direction of unfettered speculation. It's an occupational hazard.

As someone who regularly develops on both platforms, I declared that the iPhone represents the future of Mac programming. The iPhone, I posited stated, offers a great new platform without the need to be fully backwards compatible like the Mac. Our own Victor Agreda challenged me to back up that position. After a bit of time and thought, I decided to do so in this post.

My key point is this: Apple's engineers have learned a lot of important design lessons during the history of OS X. When the iPhone debuted, it gave those engineers the chance to rebuild an OS and an API from the ground up. Those engineers could craft a platform and its libraries that built on the Mac's successes without dragging along its less fortunate design decisions. Yes, there were some lemon frameworks that initially made the grade, but over time, Apple has reduced their number.

Even now, Apple continues its iPhone design process, adding new frameworks and APIs at a prodigious rate. The iPhone OS remains a work in progress, developing in ways and directions that the initial release two years ago could not have anticipated. And Apple does this, knowing fully that the closed platform allows them a great deal of design freedom that would not have been possible on the open Macintosh.

In contrast, consider in how many ways the Mac's successful history drags the platform down. A commitment to existing APIs and historical design practices show up in nearly every Mac development project. The simple elegance of the iPhone's built-from-the-start-as-Objective-C 2.0-based API is largely missing from Cocoa libraries.

Whether you're working with buttons, menus or simple text views, the iPhone development approach simply works better: beautiful 2.0-style properties, consistent API design, better-thought-out object inheritance trees, and so forth. With the iPhone, you see a great new platform evolving without the need to be fully backwards compatible

Snow Leopard, with its minimal API changes has bought the Macintosh a few years of stability. But I think it's time for Apple to rethink the platform as a whole, re-imagining its API through the lens of current iPhone OS development. While Snow Leopard offers Apple the room to stay still for now, I can see Apple moving forward in a separate engineering effort to Cocoa Touch Mac, a hypothetical cross-platform OS that supports general development on iPhone and future Mac devices like my imaginary snow-princess-rainbow-pony-iTablet.

The ghost of NeXT-past, as TUAW-colleague Joachim Bean puts it, still haunts us. It's time to exorcise the unhelpful bits of that pervasive spirit and usher in the new age of the iPhone and its API design examples. Mac OS X is, and has been, a superb development platform. What I'm suggesting is that iPhone OS might just be a better one.

Stepping up to a shiny new 3GS? Thinking about selling your old iPhone on eBay or craigslist? Don't forget to wipe!

I buy iPhones from time to time to unlock and offer to our local customers. One such phone arrived today and I eagerly opened the box to get things prepared. After charging the dead iPhone for a while, I powered it on and was greeted with tons of personal information about the previous owner.

The phone was loaded up with three accounts full of literally thousands of emails, 107 contacts, 974 songs, a few dozen photos and a handful of apps -- all still happily filling the 8GB. There were faxed checks related to the previous owner's sales position, visual voicemails available to anyone's ears, and a huge log full of text messages.

The previous owner hadn't deleted anything before sending his iPhone off to a complete stranger! While I was taking care of that important step for him, I thought "This is a perfect opportunity to save some TUAW readers from this sort of embarrassment, not to mention potential ID theft, with a quick reminder."

Clearing all of the data from your iPhone was made simple with the 2.0 firmware update last year.

1. Go to Settings
2. Tap on General
3. Scroll all the way down and tap Reset
4. Choose Erase All Content and Settings
5. Confirm (twice) that you REALLY want to lose everything

Make sure you have it plugged in, as the process will take quite a long time, "about an hour" according to the warning. But, believe me, it is time well spent!

Once the process is complete, you'll be left with a "factory fresh" installation of the iPhone OS with no trace of you or your data, and you can safely sell it and upgrade to the latest and greatest model. Oh, and do me a favor -- if I'm the auction winner, include a working sync cable this time!

So here's something interesting, if you're curious to know what features might be in iPhone OS 3.1. It seems YouTube is chock full of videos shot in what seems to be defiance of Apple's NDA for 3.1 features. A couple of gems hint at expanded copy/paste functions, and there's one video which we could swear might hint at a real-time zoom... perhaps not just for photos but for framing video?

Anyway, it's a bit of a mining expedition, as searching for specific [REDACTED] methods or properties yields best results, so don't get all hot and bothered thinking you'll peep an iPad by searching for "setAppleTabletSize" or something. In fact, all of these could be fake, although the sheer number of videos seems to suggest something other than a grand deception.

The iPhone Blog is reporting what's purported to be in the next, and hopefully imminent iPhone update to version 3.1. As we've reported, developers were seeded with the beta Tuesday.

Here's the list:

• Voice Control now works over Bluetooth
• Updated AT&T profile to 4.2 (MMS is now enabled)
• Improvements to OpenGL and Quartz.
• iPhone vibrates when moving icons
• Non-destructive video editing means trimming a clip no longer saves over the original video but gives you the option to "Save as copy..."
• APIs to allow third party apps to access videos and edit them.
• Updated modem firmware to 5.08.01

If true, it will put smiles on a lot of iPhone owners' faces. The omission of Bluetooth voice control seemed downright silly. Losing your original video after an edit seemed pretty counter-intuitive as well. It also appears MMS will appear in the update, but that only matters if AT&T turns it on.

No firm dates for the update of course, but if the above is accurate it will be a good one.

Thanks Brad for the tip

MSNBC recently added an iPhone app to the store, so we thought it was a good time to take a look at a few news apps.

The gold standard for news on the iPhone is the USA Today app. Love them or hate them, the USA Today punchy writing style feels right at home on the iPhone. News can be received from a wide range of mobile sources, and it's the design of this app that makes it stand out. I would love to have the authors pack my suitcase the next time I travel, since they have found a way to cram an incredible amount of information into a very small package. Using persistent buttons on the bottom of each screen, you can get to Headlines, Sports Scores, Weather, Photo Galleries, and Snapshots (which are a set of insta-polls), from anywhere.

What makes it special is that, along with the local weather, at the top of most category screens there is a sliding set of sub-categories allowing you to get to just what you want in no time. For example, if you wanted to get the score of the Yankees' game, just tap Scores, and the sub-categories of NFL, MBL, NBA, NCAAF and NCAAB appear at the top of the screen. Tap MLB and there it is. Two taps total.

Similarly, tapping Headlines brings up sub-categories of: Top News, News, Money, Sports, Life Tech and Travel. When in any category, tap Top Stories and you can set a default for the type of story you would like to see first. For example, under the sub-category of Money, you can choose to set the default to: Top Stories, Markets, Economy, Cars, Personal Finance or Industry. Set it up once and you'll be able to drill down to specific results in a universe of information with just a few taps.

Tap on Share Article and you can Email, Text, Twitter (your Twitter client can be chosen in the setup pane), or log into Facebook. in all the apps covered here, you can share, but this has the most robust feature set of the lot. The fit, finish and depth of the app is, okay I'll say it -- awesome. Weather is location enabled, the Picture Galleries are extensive and under Snapshots there are nine running polls in each of the four sub-categories of News, Sports, Money and Life. USA Today is not just for hotel rooms anymore.

We had a quick chat with Dr. Wm. Cameron Powell of Airstrip Technologies at the 5th Avenue Apple Store this morning, talking about his company's data visualization and monitoring tools for hospital use. Airstrip's FDA-approved application for OB monitoring is already on the App Store in demo form, and is being rolled out in sites around the country; the company was featured in the WWDC developer showcase video, which has really ramped up the volume of calls and emails that Powell and his team are getting from large medical systems integrators.

Airstrip's forthcoming Critical Care product is in the final stages of testing before rollout; the company also has cardiology, imaging and lab test versions coming soon.

Freeverse president Ian Lynch Smith and dev lead Bruce Morrison were among the crowds at the 5th Avenue Store early this morning, and both are enthused about the promise of the new iPhone hardware for gamers. We took a few minutes to talk to them (pardon the loud store noise).

While I trashed Vodafone NZ's pricing in a previous post, in at least one way it's far ahead of U.S. telco giant AT&T: internet tethering using the iPhone is already possible over Vodafone's network without resorting to lengthy, kludgy, and unsupported hacks. Who knows how long tethering will stay supported here, or how long it will take before Vodafone remembers to charge extra for it, but for now, tethering is go in the Southern Hemisphere.

Tethering works over both USB and Bluetooth. Using USB to tether simply requires enabling internet tethering in the iPhone's settings, then plugging the iPhone into an available USB port on your computer. The Mac will automatically recognize the tethered iPhone, and your connection will be up and running.

Bluetooth tethering obviously requires enabling Bluetooth on both your iPhone and computer, and then selecting "Connect to Network" from the Bluetooth drop-down menu. Once again, the rest of the setup is automatic -- it really doesn't get much simpler than this.

The speed of the internet connection appears to be comparable to the iPhone's standard mobile speed using USB, but Bluetooth was only about half as fast. I didn't remain tethered for long for fear of gulping down my meager monthly data cap, but for the time I used it, tethering worked with no issues whatsoever.

For my money, having tethering available in little ol' New Zealand long before the U.S. will have it puts AT&T in an even less flattering light -- while AT&T has far more users spread over a much larger area than Vodafone NZ, AT&T also has more towers and more money to pour into their infrastructure.

Any other international iPhone users managed to get tethering working on their networks? Sound off in the comments, and be sure to let us know what network you're on.

Read on for a pictorial guide to enabling tethering over Bluetooth.

It's that time of year again. In the US, schools are emptying, weather is heating up and all sorts of developers are readying to wend their way to San Francisco for Apple's annual Worldwide Developer Conference, or WWDC.

Sure, the noncoding masses are expecting a hardware announcement (new iPhone, anyone?), but developers are really salivating over improvements to OS X in the upcoming Snow Leopard (10.6) release, and iPhone OS 3.0. After all, with great hardware comes awesome software. Apple might even have some surprises in store for us.

TUAW will be at WWDC during the week, and if you're a developer for iPhone or the Mac, we want to talk to you! Be sure to polish your elevator pitch, as we'd like to shoot as many demos as possible. Plus, we're attending the Parallels party (RSVP here), the iPhone Launch Party and maybe a few others, so there will be plenty of chances for your shot at fame. If you'd like to get in touch with us before the event, you can email us at wwdc at tuaw (dot com). See you in San Francisco! You can also join us online and on the phone during Sunday night's talkcast, where we'll be talking about the final round of preconference rumors and expected announcements.

For those you not attending, stay tuned to TUAW as we liveblog the keynote, dig into the announcements, and show the newest of the new apps being demoed at the event.

One of the relatively unsung features of the upcoming iPhone 3.0 firmware is that the new version of Safari for iPhone will use geolocation. This means that the browser can request location information from the iPhone's GPS receiver, and can also provide that location information to websites that you're visiting.

ComputerWorld's Seth Weintraub reports that the beta versions of the firmware are working well with sample web-aware websites. This capability is not only planned for the iPhone's implementation of Safari, but many upcoming browsers for Mac as well.

Geolocation capabilities make it simple for developers to create web apps that no longer need to ask you for an address or zip code. Google, for instance, is planning on making their Latitude application a 3.0-only web app rather than a standalone application on the iPhone. Latitude will leverage the geolocation features of Safari by knowing exactly where you are at a particular point in time and sending that info to the Latitude servers, then returning the whereabouts of your friends while informing them where you are.

For those of you who don't want your 3.0-enabled iPhone to let the world know exactly where you are, remember that you can always turn off Location Services in the General Settings or just answer "Don't Allow" when asked if Safari or a particular website would like to use your current location.

But you knew this, right? Fire up your downloaders, another update from Apple means the digging has already begun for a) new features or updates, b) hints for a new iPhone.

Thanks to everyone who sent this in! I'd like to note that we broke this via our Twitter feed several hours ago. Even if you don't "do" the Twitter dance, it's a good way to catch breaking news.

Ars is reporting the 3.0 speed improvements to Mobile Safari's JavaScript engine range from 3x to 16x -- a blessed boon to web developers everywhere. No one seems to know if Mobile Safari will be sporting Nitro or SquirrelFish or what, but whatever it is, it'll be faster. If you check out the benchmarks originally posted on Wayne Pan's blog, iPhone OS 3.0 blazes past 2.2 in every category except divisions (the benchmarking tools are available at Craig Hockenberry's blog here).

It's nice to see progress, but I don't think anyone expected Apple to let the JS engine in Mobile Safari lay fallow for long. Every day browsers like Opera Mini and Android's WebKit-based browser are getting better. Heck, even WinMo's version of IE is supposed to support H.264, Flash and Silverlight. Will the upgraded js engine and technology like CSS3 and Canvas draw more developers to iPhone web apps? I doubt it, but the speed improvements will make many browser-based services feel more responsive. That's certainly a win for consumers.

Tuesday's iPhone OS 3.0 announcement has left the interwebs even more iPhone-obsessed than usual. If you find digging through all this information overwhelming (or, if like me you were out of town when OS 3.0 was announced), check out this round-up of news, opinions and videos. The only thing missing is a beta copy of OS 3.0 and that's already floating around various torrent sites.

If that's not enough, be sure to check out our continuing iPhone OS 3.0 coverage.

SDK 3.0 brings more NDA fun -- Much to the chagrin of many iPhone devlopers, the NDA is back for SDK 3.0. At Arstechnica, our pal Erica takes on what this means for developers. Let's just hope the NDA is lifted as soon as 3.0 is officially released.

OS 3.0 Screenshot Pr0n -- Pfft, what NDA? iLounge has put together a great gallery of iPhone OS 3.0 screenshots, showing off what's new and improved. Love it.

iPhone OS 3.0 vs. Android -- Lifehacker has a pretty neat comparison of features that are currently avaialable in the iPhone 2.21, stuff that's coming in OS 3.0 and what's available and coming for Android. As someone who has spent a LOT of time using both the iPhone OS and the T-Mobile G1, I'd just add that hardware and UI is actually just as important as "features" when comparing the two platforms. Right now, the iPhone absolutely cleans Android's clock -- despite having fewer "features" -- because the hardware is better (that G1 keyboard is terrible), the UI is more thought-out and the third-party software is better by leaps and bounds.
