Imagine that you're at home one night and want to send a message to your partner or roommate or someone else, but you really don't want to get out of your chair, and you don't want to yell loudly enough for them to hear you. So pick up your iPhone, but you don't want to send an SMS or call them. Surely there's an app for that...

Actually, there are several; some better than others. Take Texter for example. For 99¢ you can send messages back and forth with other people on the same Wi-Fi network. Sounds promising, right? After all, SMS costs are ridiculously expensive, so why not pay a $1 fee to buy an app to send messages back and forth.

The idea isn't bad, but the implementation is. First of all, Texter only works over Wi-Fi. And not just any Wi-Fi. Both users must be on the same Wi-Fi network. But maybe everyone in your family has an iPhone or iPod touch, so you're still willing to give it a try. Well, don't open your wallet just yet, because there's one more detail that we need to mention -- Texter doesn't support push notifications. Since Apple doesn't allow third party apps to run in the background, the end result is that you can only communicate with other Texter users if they already have the application open on their iPhones.

I can't even imagine a "use case" for this application. Who would sit around with their iPhone on, running an application in the hopes that maybe someone in the same home/office with the same application might want to chat with them? It simply is never going to happen.

If you want to avoid SMS charges, but still want to send quick messages to other iPhone users, why not use AOL's free (ad-supported) AIM iPhone app? It works over EDGE, 3G, or Wi-Fi, supports push notifications, and also allows you to connect with a slew of other people besides iPhone users.

Maybe you don't like AIM or SMS. Maybe you really like the idea of having an iPhone app that is quick and easy and doesn't require any login or giving away your cell phone number (like SMS does). If that's the case, checkout the 99¢ Ping! app for iPhone. It also works over EDGE, 3G, and Wi-Fi and supports push notifications. You'll also have that healthy self-satisfaction of knowing that you are only communicating with other red blooded iPhone/iPod touch users.

I'm sure there are a slew of other alternatives to SMS for the iPhone that work over EDGE/3G or Wi-Fi and support push notifications. Tell me about your favorites in the comments (bonus points for including an App Store link).

For many iPhone owners in the U.S., the fact that you're tied to AT&T as the wireless carrier has been a serious problem. As an example, until this week, I was lucky if I got 2 bars of signal strength on EDGE at my house and I never had 3G service. Now, for some inexplicable reason, I'm able to get a full 5 bars on 3G on the top floor of my house and about 3 bars on the lower floor.

Unless you're fortunate enough to have a similar miracle take place near your home, you may need to take advantage of AT&T's upcoming 3G MicroCell service. This service literally puts a tiny Internet-attached cell tower in your home or office, blasting out 5 bars of 3G goodness to about a 5,000 square foot area.

The 3G MicroCell comes at a price, of course -- the device is rumored to cost $150 and there will be no monthly charge if you wish to use your existing minutes. You can also add unlimited phone calls through the device for an extra $20 per month, so if you primarily use your iPhone in one location, it might be cheaper to get the minimum service plan for the iPhone and just use the 3G MicroCell unlimited plan for your calls.

AT&T's rollout of the 3G MicroCell service will make the iPhone available to a wider audience of potential users, and may also benefit the overstressed AT&T network by decreasing the number of voice and data calls using the regular cell towers.

At the present time, AT&T is testing the 3G MicroCell service in Charlotte, NC. You can check availability of the service by visiting the AT&T site.

I like to joke that "Iowa is a great place to live, but I wouldn't want to visit." Residents often complain that there's nothing to do (other than milk cows and shuck corn). One can only stand so much antiquing.

But we do have a few things going for us: clean air, relatively light traffic, lots of space, and perhaps the best cell phone plan for the iPhone.

Recently, reader PC Drew, a US Marine living in Japan, sent us a note to let us know about the challenge he had in finding an iPhone plan while visiting his wife's family. A contract plan was out of the question, of course, because of his length of stay and the fact that he's still under a two-year Softbank agreement in Japan. And due to AT&T's, shall we say, "perplexing" lack of a prepaid plan for the iPhone, the official carrier in the States wouldn't help him.

He could have stopped by a Best Buy and picked up an O2 Universal SIM Card for less than $10. That would have provided the ironically-named PC with $0.17 per minute calls but that's it -- no data, no included text messages, and no tethering ability.

After searching a bit for a prepaid solution, he stumbled across the MEGAtalk Nationwide plan from regional GSM carrier, i wireless. This no-contract, no-credit-check offering gives the customer 30 days of unlimited calling, with roaming and long distance, for $49 plus taxes.

But wait, there's more! Not only did PC get unlimited voice minutes, but he also had unlimited SMS texting and, here's the kicker, unlimited data usage. And, with the proper hack, i wireless customers can tether their iPhones for free. Yes, you read that right... free tethering on an unlimited data plan!

Of course, getting a service plan from an unofficial carrier (read: non-AT&T, at least in the United States) requires your iPhone to be SIM-unlocked. This has become much easier over the past two years and most cell phone shops can perform the procedure if you're too nervous. PC had already performed the necessary steps, as he often finds himself in areas that aren't exactly covered by his Softbank contract.

Okay, now for the downer. Because it's a T-Mobile affiliate, i wireless doesn't offer iPhone-compatible 3G service. In fact, they only offer EDGE speeds in their Iowa-based footprint, unless you're traveling to an area with T-Mobile 3G. As a result, that unlimited data is a bit crippled speed-wise, but it's still a heck of a deal.

So, if you're planning on traveling to Iowa -- say, to Fort Madison for the 62nd Annual Tri-State Rodeo in September -- or if you're "lucky" enough to be stuck living here, you might want to take advantage of what's probably the most economical cell phone service plan available for the iPhone anywhere in the USA.

UPDATE: Quite a few readers asked if this plan is available outside of Iowa, so I contacted i wireless directly to find out more about its policy. Yes, you can sign up for this plan, even if you don't live in the i wireless footprint area, however, the representative I spoke with pointed out that this plan may expire at any time, which would seriously affect the customer's ability to use his or her phone effectively. If you are interested in further details, please contact i wireless directly.

DISCLAIMER: I own a computer and cell phone store that sells this particular prepaid plan. But the above story is absolutely true; PC Drew did contact TUAW to brag about his bargain find, without knowing me or my connection to the product.

We covered Jason Rohrer's Primrose when it first came out -- the creator of Passage, a critically-acclaimed indie game, had taken his first steps onto the iPhone with an abstract puzzle game, and in this latest interview with Edge, Rohrer says he's on the iPhone to stay. He says that when he first moved from strictly art/indie games to more commercial development on the iPhone, he worried that he was selling out: he wasn't a fan of cell phones at all or any Chinese-made gadgets sold by American companies, and yet the iPhone's platform seemed most "palatable" to him in terms of making games and a little money from them.

And yet he says the iPhone still has pros and cons -- even in an "open source, free software" world, Apple's system offers a choice: you can buy a packaged-up version of the software and throw a little money back to the developer (not a ton -- he says you've still got a better chance at making a living from Vegas than you do from the App Store), or you can still try building and installing your own version on your iPhone. As an open-source developer selling apps on the App Store, he says, "you're charging for the service and convenience, not the content."

Still, he echoes the sentiments of lots of other developers: "There is no quality filter, except for the whims of the masses." Apple's App Store offers up an intriguing system for many indie developers like Rohrer, who want to earn a little money for their games without setting up all of the complexity and burdens of a more traditional publishing channel, but it's still tough to keep from getting lost in the mix.

Back when we looked at Radar, a photosharing site with an accompanying iPhone app, I mentioned that while Twitter had monopolized the "text exporting" function from your iPhone, there would be a slew of companies to try and grab the rest of the media you want to broadcast. Radar, I said, wanted to be the photo app. And AudioBoo, it appears, wants to be the audio app (we've yet to see a strong video contender pop up with the 3GS, though YouTube is certainly serving for now).

I've been using AudioBoo (iTunes link) for a few weeks now, and I have to say, it definitely does what it says on the box: after a short signup session and the installation of the app to your iPhone, you can record and upload (and almost more interesting, listen back to others') audio quickly and easily.

You hit record, can talk for a while (i haven't hit a limit yet, though three minutes is what I originally heard, and that tends to be about right for these little mini-podcasts), then hit stop and upload, add a picture, title, and tags, and a few minutes later, your audio is right there on the web for everyone to hear. I've used it on my EDGE phone and my friend's 3G, and I have to say the experience is better on the 3G -- the upload speeds are much better (I generally have to wait on my iPhone until I get on Wi-Fi to upload the audio), and to my ears, the audio sounds better. Here's a recording I made at a Cubs game on my 1G with a few friends, and a recording my friend made on his 3G at a restaurant. Edge works, obviously, but the 3G seems to work better.

In a shot across the iPhone's bow, Palm is launching its new Palm Pre smartphone the weekend before Apple's Worldwide Developer Conference. This means any iPhone announcements at WWDC will be undoubtedly compared to Palm's new platform.

The Pre handset will cost $200 after a $100 mail-in rebate, and if you sign up for a two-year contract with Sprint. The monthly service costs roughly the same as AT&T's iPhone plan but offers unlimited text messaging -- a $20 option with Ma Bell.

Electronista points out that the Pre has some small technical advantages over the iPhone as well: a three megapixel camera, an optional inductive charger, and EVDO networking. Depending on the area, EVDO can be faster than both EDGE and GPRS, but not faster than HSDPA (the latter of which AT&T is rolling out across the U.S.). In any case, AT&T is already preparing its sales staff for the looming battle.

Also, Sprint claims that having a Pre will cost $1,430 less over the two-year contract period compared to owning an iPhone for the same period.

Meanwhile, for those of us on Verizon, we'll just have to make do with calculators connected by string. Which reminds me -- you all got the notice Verizon was upgrading us to nylon cord this week, right?

No, not the Edge network from AT&T, but a rather unique app from Mobigame that uses the motion sensors of the iPhone and some powerful animations to make for a unique gaming experience. Looking a bit like something out of the movie Tron, Edge allows you to control a cube through several hazardous environments and traps that get more and more complicated as you move along.

The best way to get an idea of what the game looks like is with this YouTube video Mobigame has posted. Edge has been available on other platforms like the Sony Ericsson handsets, but it will debut on the iPhone and iPod touch next week. There are 26 different mazes to navigate, using the iPhone touch screen and accelerometer.

Edge has been nominated for several gaming awards in Europe and has the potential to be a major hit on the iPhone/iPod touch. We'll be anxious to try this one ASAP.

After the iPhone debuted, I posted this poll on TUAW, where I first got a sense of how much data YouTube videos and Mobile Safari web pages were pulling down through the network.

We're now about two months into iPhone 3G and I thought I'd repeat the exercise. How much data are you using on that 3G iPhone of yours? Are you still at 2.5G/EDGE levels of usage or has the 3G data bumped you up into new territory?

Pop into your iPhone's Settings > General > Usage pane and check out your Cellular Network Data usage stats. Drop a note in the comments and let us know about how much data you're actually using per month. (Assuming you haven't reset your phone, there will be about 2 months of data there.) And if any of you 1st Gen EDGE iPhone users have comparative data for month-to-month usage (rather than your total stats), that would be great to compare with the 3G numbers.



So have at it, readers. How much data are you using?

Earlier today, many iPhone owners on the east coast (including yours truly) were experiencing data problems with AT&T. Specifically, my data transfer all but disappeared, including web and email, over EDGE. The weird part was that my iPhone was reporting a strong signal. It seems I wasn't alone.

Electornista is reporting that the issue affected users from New York to Missouri, Massachusetts and North Carolina. AT&T responded and, as of this writing, it's been worked out. A representative said, "There was a routing issue affecting some wireless data use in the Northeast region ... technicians determined the cause and restored service at 11:56AM EDT."

So, flip on your iPhones, east coast-dwellers. We're back in business.

A few weeks back on the Talkcast, we had an interesting little discussion about just where Apple's boundaries were on the App Store -- so far, you really only get kicked off if you charge too much, if your apps vibrate wrong, or if you steal someone's copyright. Oh, and there's that one more little exception: if you provide folks with the ability to tether the iPhone's networking ability to your own Mac.

But now the rumor mill says that last one might just have been removed because Apple is planning a tether solution of their own. Gizmodo claims that one of their readers is corresponding with His Steveness himself (a fact we find obviously dubious, but hey it's Friday of Labor Day weekend, so we'll give 'em a pass). You'd think that Steve Jobs would reveal the fact that AT&T and Apple were trying to offer a tether solution through a slightly better venue than a quickly jotted "Sent from my iPhone" email, but remember how we first heard about the SDK -- the man knows how to stick important pieces of news in strange places.

The original emailer mentioned tethering for the fee of an extra $30 a month (which seems exorbitant considering that Netshare did it for a one-time charge), but then again, AT&T's networks are going to get even more waterlogged should something like this come down. So odds are if Apple does work out a deal, it's not going to be cheap.

Wired has published the results of the iPhone reception survey they were running, and clearly Antarctica needs way more coverage. But they also pulled a lot of useful data out of places where people actually live, and it probably doesn't surprise you.

3G performance is slow almost all over, especially in cities where the 3G service is getting overloaded. If you want to have fast speeds, hang out in Germany and the Netherlands -- those folks had the fastest speeds (and it's no coincidence that the 3G network there has three extra development years on its American counterpart). The worst reception is apparently in Australia, as Optus and Virgin users had their iPhones chugging along at just 759 Kbps.

What can we draw from this? Just like those Swedish scientists told us, it's the service, not the phone. But you know what Mark Twain said about statistics, so just in case you want to draw your own conclusions, Wired has kindly made a Google Spreadsheet of all the data available to anyone who wants it. Anyone want to try putting together that heatmap?

Not to be outdone by Qik, Flixwagon started offering their live streaming client for the iPhone 3G/2G this week. Flixwagon offers streaming video over WiFi or over the cellular data connection. In addition, the application offers 12 frames-per-second video. The company claims that they have very fast signup right from the iPhone, and the ability to change titles/details while broadcasting.

The last time we mentioned Flixwagon, it was still in beta, but they have finally opened up the service to anyone who has a jailbroken iPhone with either Cydia or Installer 4. The application weighs in at only 98 KB. For more information about this video streaming service, visit the Flixwagon blog.

If you are one of the lucky ones who got in on the GrandCentral beta, then you might be interested in a new iPhone app that integrates with the GrandCentral service. Grandialer (iTunes link) allows you to use your iPhone to call people using your GrandCentral telephone number.

The service can be used on EDGE since it's not a VoIP service. The application works by connecting your calls through GrandCentral and ringing back your iPhone. To set up the application, you just need to specify a ringback number for GrandCentral to call you back. To do this, just navigate to Settings > Phone number in the Grandialer application.

Grandialer is a free application and is available today on the App Store. For more information on the application you can visit the developer's site.

When the App Store first launched last Thursday, I saw Pandora and AOL Radio and immediately wondered if they would work on my first generation iPhone using EDGE. The quick answer is yes, however, you do make some sacrifices in one of the applications. Read my full review below to get the full details.

About Pandora (Download Link)
Pandora is a part of the Music Genome Project and allows you to create "stations" of your favorite artists. Pandora then pairs those artists to others you might like and plays an unlimited playlist based on your favorite artists. Pandora tracks your likes and dislikes and will play songs based on those results. Pandora lets you find new music for free, and who can argue with that?



About AOL Radio (Download Link)
AOL Radio is a CBS Radio partner that provides online streaming radio stations. Unlike Pandora, AOL Radio is a true streaming radio station in the sense that you can play local stations which support in-audio advertising. AOL Radio can use the location feature in order to find CBS affiliate stations that bitcast near you.



User Interface
Both Pandora and AOL Radio follow a similar user interface design: they both look like the iPod feature on iPhone/iPod touch. Both of the interfaces are nice, however, I have the same gripes for both. The volume controllers in both seem to be independent of the iPhone's volume controller. This can cause the audio to be distorted if you turn it up too much in the applications themselves since you can use the volume buttons on the side to control the audio volume as well.

Secondly, I would love to be able to quit the application and have the audio keep playing (I know, this is an Apple/SDK restriction, but it would still be nice). You can, however, lock the phone and keep the audio playing (which is a nice feature).

Both applications allow you to purchase the currently playing song from the iTunes WiFi Music store. AOL Radio also provides a link to find out more about the currently playing song on AOL Radio's site.

WiFi (or 3G) vs. EDGE Use
When you are playing the music over WiFi (or the 3G cell network), you get awesome audio quality. Both applications seem to provide audio quality that matches that of purchased iTunes songs. On EDGE, however, AOL Radio falls short by providing very low quality audio (I would guess 56k audio). However, Pandora on EDGE seems to maintain good audio quality when you have a signal that is greater than 2/5 bars.

So, who wins?
Since both of these applications are absolutely free and have equal pros and cons, I would recommend downloading both to see which one fits you the best. If you are on a 3G iPhone, both will work well no matter where you are (assuming you're within 3G coverage). However, if you have a 2G iPhone, you might prefer Pandora because it provides better audio quality over EDGE. You can download both applications by clicking the download links above.

Disclaimer: The Unofficial Apple Weblog and AOL Radio are both owned by AOL.

My relationship with my iPhone hasn't been an easy one. On the one hand, it's an absolutely brilliant platform -- I just love programming for it. On the other hand it's a money hole. To keep it legit, I'm forking over a wad of cash each month to AT&T and from there on to Apple (not to mention the $99/year new iPhone play tax). One of my biggest decisions on that end involved giving up my data plan. Leaving the $20/month data plan behind as my "optional extra" has saved me $240 over the course of the year.

Read on for more about the iPhone and EDGE and my 3G service dilemma.
