Recently, we reported on AT&T's push to make it easier for iPhone & iPod touch users to connect to their Wi-Fi Hot Spots. One of our readers, Jamie Phelps, pointed out on his blog that AT&T's Wi-Fi service is not actually a "secure connection," as is advertised in various places on their website; we had overlooked this, and mistakenly reinforced the company's shaky claim in our post.

This brings to light an important point about wireless networks and security, however. It's really easy (and sadly all too common) to hop on to an available wireless signal in your office, at the hotel, or your favorite coffee spot and not even think twice about logging in to your e-mail or checking your bank balance.

What many users don't realize is even though the server you are connecting to (i.e. your bank's website) may employ several layers of security, the connection between your computer and the wireless access point is very likely to be unsecured. Anyone who is within range of your computer can trivially monitor the traffic being sent between your computer and the access point, allowing them to see what websites you may be visiting or capture details about other services that you may be connected to. This isn't because of some gaping vulnerability or software bug, it's just an inherent part of how wireless networks work.

So, what can you do to protect yourself? Read on for a list of simple steps you can take to ensure that your wireless connection is safe and secure.

Get your mind out of the gutter! I'm talking about the Quicky Jr II USB wireless signal booster, which is a little USB dongle / antenna that plugs into a USB port on any Mac that is running Mac OS X 10.4 or newer. This little device, from QuickerTek, purports to let you wander up to three times the distance you normally can, and still receive a nice, strong, and encrypted wireless signal.

The US$89.95 Quicky Jr II comes with an easily-installed USB driver that lets it work with your 802.11n/g/b networks, including those that are powered by an AirPort Extreme Base Station. While I'm usually dubious of any device that claims to increase wireless range unless it is pitched by the late, great Billy Mays, the Quicky Jr II appears to be just what it says it is; a powered USB Wi-Fi antenna. In theory the larger antenna size and a built-in USB-powered amplifier could help boost the signal, then route it to your AirPort circuitry.

Rather than speculate on how well devices like this work, I'd like to ask our readers. Do you have any experience with this or similar products? Do they work as advertised? TUAW wants to know.

Last night Apple released a firmware update for Time Capsule, AirPort Extreme, and AirPort Express Base Station with 802.11n. Here are the fixes:

• Fixes some problems with extending and maintaining connectivity with extended networks
• Fixes an issue with clients that enable 802.11 "Power Save"
• Fixes connectivity issues with some third-party devices
• Fixes an issue when the base station is configured for PPPoE
• Fixes some Back To My Mac issues with connectivity and support for third-party routers

All of those sound like issues that could affect quite a few people -- especially those with (gasp!) "third-party" devices. I've certainly had issues with Back To My Mac using a Netgear router, so we'll see if this helps. In any event, firmware updates are recommended especially if you've had any of the above symptoms.

AT&T today announced that it will begin upgrading its network to the faster High Speed Packet Access (HSPA) 7.2 technology later this year. The 3G network upgrade will not be completed until 2011, at which time AT&T plans to start deploying the 4G Long Term Evolution (LTE) network. This is contrary to previous roadmaps, which showed HSPA+ (20+ Mbps) deployment occurring prior to the move to LTE.

Devices compatible with HSPA 7.2 3G networks are capable of a theoretical peak download speed of 7.2 Mbps (megabits per second), or almost a megabyte per second. While the current iPhone 3G does not support HSPA 7.2, many of the rumors circulating about a next-generation device include HSPA 7.2 compatibility. AT&T's press release also noted that "multiple HSPA 7.2-compatible laptop cards and smartphones" will be available later this year.

The AT&T network is currently undergoing other upgrades, to the tune of over $17 billion of capital investment. AT&T is still deploying more 850 MHz spectrum for better coverage and in-building 3G reception. The 'Death Star' is adding fiber-optic connectivity and more capacity to many cell sites in anticipation of the higher bandwidth required by HSPA 7.2 and LTE, and the plan is to add almost 2,100 new cell sites in 2009.

AT&T also noted that they're working on customer trials of AT&T 3G MicroCell, using femtocells to improve in-building wireless coverage.

We're back with another edition of Ask TUAW! This time around we've got questions about recording audio, troubleshooting wireless issues, the best place to go for web hosting and more.

As always, your questions and suggestions are welcome. Questions for next week should be left in the comments. When asking a question please include which machine you're running and which version of Mac OS X (we'll assume you're running Leopard on an Intel Mac if you don't specify). And now, on to the questions!

Petre asks:

I just bought a new guitar and I'm thinking about using it to record some of my songs with my new iMac. Any recommendations for a good method of connecting a guitar so I can record?

Fortunately, you're in luck, in that the Mac is made for people trying to do just what you want to do. There are several options to accomplish this and it really just depends on how good you want the audio to sound and what your budget is. To get the best possible quality, you're going to need a few items.

First, you're going to need some recording software. Fortunately, that's already on your iMac as you can use Apple's GarageBand for all your entry-level recording needs. Second, you'll need some sort of digital audio interface that connects your guitar's output to a USB or Firewire interface on your iMac. Some good ones to take a look at include the M-Audio MobilePre, the M-Audio Firewire Solo or the Line 6 Tone Port series. Then, all you need to do is plug your guitar into the converter and the converter into your Mac and you're good to go. Of course, you'll want to be sure and update the driver to the latest version and read the manual to get the most out of your converter.

If you're not as concerned about audio quality, you can also use a converter cable, such as the Monster iStudio Link, to connect your guitar directly to the mic input on your iMac. That will allow you to record directly into your Mac but won't give you the best possible audio quality or level of customization you could get from a digital converter.

It's impossible not to love a blog post that begins, "I found a way to remote control my R2D2 with an iPhone."

The video above shows the author, ggpipe, using the iPhone's accelerometer to control R2's dome. Pretty cool. In the future, he plans to use the phone to send text to R2's logic displays. We love it and can't wait to see a fully assembled, iPhone-powered R2D2!

It's great to see people extending the iPhone's capabilities, and homegrown remotes are a cool choice. A couple of weeks ago, we posted a story about a guy who turned his iPhone into an R/C aircraft controller, and last year we saw Delphi's Wireless Vehicle Access software that lets you control many of your car's functions. Keep up the good work, everyone!

When all of those iPhone 3.0 features were first announced, one of the features that stuck out most to me was the incoming A2DP ability -- the new iPhone OS will let you stream out music to a Bluetooth source, like headphones... or your car. And over at Cars.com, the guys got their hands on a Toyota Venza with Bluetooth capability, and did just that, as you can see in the video above. It's pretty slick -- no wires, no annoying pairing, just hit the Bluetooth button on the iPod, choose the car's Bluetooth source, and press play. We're not sure about audio quality (it should be at least listenable), but it looks super cool.

There are, as usual, some catches. I for one was disappointed to hear that this A2DP ability won't work with first-gen iPhones like mine -- you'll need to have a 3G to do something like this. And of course, this will require the iPhone OS 3.0, which isn't technically out yet (though devs in Apple's development program are playing with it right now, which is why you can see it in the video above). And finally, you'll need a car with the Bluetooth capability, which (though I haven't owned or shopped for a car for a few years, so maybe things have changed a bit) is still kind of hard to find.

But hey, even if you're not there yet, here's a look at the future. Where we're going, you won't need wires to get your iPod playing music on the car stereo.

Our sister site Engadget notes that iDealsChina found this rendering of a silicone case for a new iPhone-like device with a smaller form factor.

iDealsChina says the case is "in production," and has many 3D images of a variety of angles. The device may be unveiled during Macworld Expo next month. The site also claims the "iPhone nano" will have three "sensors," a camera, a "mirror screen" and no 3G. The device will allegedly start production on December 20th at a rate of 60,000 to 80,000 units a day.

This falls in line with unsourced rumors of a wireless product slated for announcement at Macworld. It could wind up being the magic $99 Walmart iPhone that we've heard so much about.

The look of the new iPod nanos was leaked (famously by Kevin Rose) earlier this year as a result of a supplier showing off renderings of new cases for the device. According to iDealsChina, "...once one company starts making a mold their information is passed onto other mold companies or accessory companies through a China underground network."

It may be a personal preference, but I try not to use or abuse phones that can't survive a 3-foot drop onto concrete. That's why last week I ordered myself a sweet little Pantech Breeze.

It offers one killer feature that I refuse to live without: a dedicated speakerphone button. I have this on my beloved Kyocera Slider and I demanded it on any new phone that I would buy. The Breeze brings that to the table along with a video camera and full Bluetooth support. After rebates, the phone cost about $70 and works perfectly with my iPhone SIM.

So after unboxing my new toy, I enabled Bluetooth on the phone and opened Leopard's Bluetooth File Exchange.

BFE isn't some super-spiffy CoverFlow all-dancing all-singing phone interface. It's a simple little utility program (with the emphasis on "utility") that allows you to browse your BT connected devices and use its drag-and-drop interface to transfer data to and from the unit.

Leopard recognized my phone without incident and opened the browsing window shown here. It took just a few clicks to offload my latest pictures from the phone and drag them into iPhoto. Going the other direction, I threw a few mp3 files into my Download > Audio folder and they instantly appeared onboard, ready to play.

Obviously the Pantech Breeze isn't the iPhone (even as I end up tapping its screen and wondering why it's not responding) but in some ways, it should have been. Why does Leopard offer this fantastic Bluetooth interaction between phone and Macintosh for an also-ran third party phone, while balking at any iPhone interactions? This is the interaction that should have been on my iPhone, using functionality already built into Leopard. I wonder why it wasn't baked into the flagship Apple product of the century.

Blogger Thomas Ricker over at our sibling site Engadget posted an interesting blurb early this morning. Curious about whether or not iPhone 3G is as bad as urban legend seems to make it out to be, engineers at Bluetest in Gothenburg, Sweden, tested it against a Nokia N73 and a Sony Ericsson P1.

The results? Although the P1 was slightly better at receiving signals and the N73 a little bit better at sending signals, the difference between these two popular 3G phones and the iPhone 3G was negligible. The degreed antenna engineer performing the tests pronounced the 3G's capabilities as "completely normal."

This testing equipment is similar to that used by the FCC and mobile phone manufacturers to make sure that their phones are able to properly send and receive signals without interfering with other devices. These tests only tested the iPhone 3G hardware. There are other factors involved as well, including the device firmware and software.

I personally haven't found the iPhone 3G's reception to be any better or worse than my original iPhone. How about you? Leave a comment!

It was there. And now it's... gone. What happened to iPhone 3G tethering app NetShare?

For a while it was live on the App Store, for a meagre ten bucks. Then it vanished. And now, it seems to have vanished from Nullriver's web site, too. Their news page has no mention of NetShare.

This smells of lawyers. NetShare was designed to let you share your iPhone's connectivity with your computer. Wireless freedom for all. And quite possibly something the telephony service providers in various countries would be alarmed to see on offer in the App Store, ten bucks or no. But wait -- the App Store is vetted, isn't it? Something like this couldn't just creep in through the ventilation shafts. This couldn't just be a ghastly mistake, could it?

You can't make software just disappear from everywhere. There must be some TUAW readers who managed to get hold of a copy before it disappeared. What do you make of it? Is it working?

For the record, we have asked NullRiver for comment, but not heard back from them yet. As soon as we do, we'll add an update.

UPDATE: And here it is. No word directly from NullRiver yet, but one of the NullRiver team pointed out in the comments that they did not have a web page for NetShare in the first place. Also, the following text has now been posted on the NullRiver home page (a fact that was also noted in the comments):

"We're not quite sure why Apple took down the NetShare application yet, we've received no communication from Apple thus far. NetShare did not violate any of the Developer or AppStore agreements. We're hoping we'll get some feedback from Apple today. Sorry to all the folks that couldn't get it in time. We'll do our best to try to get the application back onto the AppStore if at all possible. At the very least, we hope Apple will allow it to be used in countries where the provider does permit tethering."

AGAIN UPDATE: NetShare has now reappeared in the App Store, at least in the US, the UK, and the Netherlands, and probably in many other places as well. You can download and play with it to your heart's content. Thanks to all the commenters and tipsters who alerted us to this.

AGAIN AGAIN UPDATE: Now we've had a reply from NullRiver, as follows: "Hi, NetShare is back on the Apple Store, hopefully for good this time! We're not quite sure why Apple took down the NetShare application yet, we've received no communication from Apple thus far. NetShare did not violate any of the Developer or AppStore agreements to our knowledge. It is unknown how mobile phone carriers may react to using the program. Or if they are even in a position to tell. My personal advice is to not go NUTS just yet by downloading tons. Also be aware that contracts/carriers vary in what they offer from country to country, please be careful your service doesn't have a metered limit, that if you go over may incur extra costs for you."

Odd, is it not, that despite all the ups and downs their app has experienced during the last day or so, NullRiver has not heard anything at all from Apple? What's that all about?

Thanks to Zoli + everyone who sent this in.

FileMagnet (mentioned briefly by Dave in his iPhone apps I actually use post yesterday) is a low-cost wireless file transfer tool for iPhone and iPod Touch. It requires you to install a companion desktop application, also called FileMagnet, which acts as the conduit for file transfer.

Usage is simple enough: drag files you wish to copy into the desktop app's window. Then open FileMagnet on the iPhone, and as long as the two machines are on the same WiFi network, they will find each other over Bonjour, and wirelessly connect. Then your files are smoothly and wirelessly transferred over. Transfer will also happen every time you sync the device, if the desktop app happens to be running.

FileMagnet is a handy place for reference materials, such as Word docs, spreadsheets, PDFs and images, that you're likely to need to carry at all times. It handles entire folders full of files, too.

There are a few problems right now, all of which are addressed on the official FileMagnet FAQ, mostly with a promise that they'll be fixed soon:

• FileMagnet cannot display iWork files (yet)
• The desktop app requires Leopard (but a Tiger version is on the way)
• You can't email files, or indeed do anything with them except view them (an email feature is coming)

Like a lot of iPhone and iPod touch apps, it's in its early days. Some features are lacking, or not as perfectly functional as you might like. But the developers are aware of the limitations and working on fixes and new features, and personally I think it's a decent value application with bright prospects for future development. I'll be watching out for updates with interest.

FileMagnet is $4.99, and available through the App Store.

UPDATE: Joshua Keay from Magnetism Studios has been in touch to say that that FileMagnet supports Tiger right now. He added that support for rotation and more file types is on the way in the next build, which will be a free update.

Apple has posted some information regarding where to buy the iPhone 3G and what to bring to the store so you can get up and running. According to Apple, in-store activations will occur at Apple's retail stores.

"Let a Specialist help you choose your iPhone, check the network coverage where you live, select a rate plan, review the contract terms, and - best of all - activate your new iPhone in just a few minutes," the Apple page explains.

Apple suggests having the following information handy to make the activation process speedy:

• Credit card
• Social security number
• Valid government-issued photo ID
• Current wireless account number and password or PIN (if you're new to AT&T)

Apple also provides information for new iPhone owners on how to organize their data to make it ready for the iPhone. All of this information can be found on Apple's Where to Buy website.

In an interview with Financial Times [registration required], Verizon CEO Ivan Seidenberg shared his company's answer to the iPhone's popularity

"...As handsets become banking tools and games controllers, he argues, mobile operators can up-end other companies' business models. 'It's very cool. And Steve Jobs will eventually get old ... I like our chances.'"

Seidenberg, who is nine years Jobs' senior, has decided to wait for his rival to "age out" of his position. This reminds me of the skinny 7th grader who laments, "Someday my bully will notice girls and lose interest in stealing my lunch money."

Or, perhaps by "old" he meant "out-of-favor" as Daring Fireball suggests. Like Jelly Shoes and Jarts, the appeal of Apple with Jobs at the wheel will eventually fade. All Verizon must do is ride out the trend, like a lobster boat in a Nor'easter.

Forget innovation and hard work. The sit-and-wait method is a good one, too. It worked for Estragon and Vladimir.

Fortunately, AT&T Wireless has a list of the major markets that have HSDPA service. Unfortunately, you have to go through the list by state and city name before you can actually click on a map and see if your house or office is in a zone of 3G love. My house, which has sucky AT&T service at this time, is allegedly in a 3G-happy area (blue on the screenshot). That's the good news. The bad news is that I'm right near the border of one of those orange zones, which indicate no 3G service.

My sister currently enjoys EDGE service in her home town of Richland, WA, but is anxious to get her iPhone connected with 3G service. I hate to tell her that she's not on the list.
