We're not having any problems, but Ars has found many people complaining about the iPhone 2.0.2 update killing their ability to actually make calls over 3G. Among the people who suffer from no-calling-itis is one guy who took his phone to AT&T and had them swap out the SIM, which somehow fixed the problem. If you're getting "call failed" on 3G, try switching back to 2G in Settings -> General -> Network and making the call again. [Ars Technica]

In similar style to the SIMable product Wilson showed you back in May, Brando now has its own SIM-hacking device available, and says it works to unlock, unchain, free, liberate—whatever—Apple iPhone 3Gs from being tied to one operator. The slim chip-and-circuit gizmo hugs the rear of your SIM and messes with the signals that go between it and the iPhone (or, indeed, a large number of other GSM and 3G phones) in a way that unlocks the device. Brando's product still requires you to cut your SIM to make room for the chip aboard it, but it looks a fairly simple operation. And it's two thirds the price of the SIMable: just US$21. [Brando]

Yeah, USB Fever just started taking pre-orders for this super thin iPhone hardware unlock tool that attaches to your SIM card, but be forewarned — it requires that you cut the corner off your SIM in order to work. If you're up for the challenge, it will supposedly start shipping on August 20 for US$35. [USB Fever via iPhone Atlas via IntoMobile]

When Apple reinvented the paperclip for the famous SIM-eject tool, it was at least a free gizmo, included in the package. USBFever clearly thought there was a gap in this market though, and have reinvented the reinvention. The new SIM-eject tool has a rubber-bung top that allows it to be stored in your iPhone 3G's headphone socket ready to be whipped out at a moment's notice when you need to change the SIM card. Probably only for really frequent SIM-swappers who don't use headphones, though, since it will cost you US$3. [USBFever]

OK, forget about what I said before. Screw the storage and the 5MP camera. I've been reviewing the iPhone 3G specs, and it's finally coming with exactly what I wanted: a genuine iPhone SIM Ejector Tool.

According to estimates based on carrier's numbers, only 2/3 of iPhones are "legally" activated, which means 1/3 of all iPhones sold are SIM unlocked and being used sans carrier contract. Here's how they arrived at this number.

The iPhone makes pretty decent use of its gravity sensor with Safari, but that's something of a kid's trick compared to the WND DUO Atom, which flips between two SIM cards as you flip it from top to bottom (or is it bottom to top?), making it easy to maintain two separate accounts. Like one for wife, one for your girlfriend—just don't turn it the wrong way. It's also a touchscreener, so the keypad and screen re-orient themselves accordingly. Hit the jump for the nitty-gritty and another glamour shot of this unlocked tri-band GSM trickster.

We finally got our gear and tried the forged SIM card method to completely unlock iPhone. It works but beware, because it depends on what kind of SIM card you use with your current unholy phone. SIM cards come in... Read More »

...Because this little 'mo could be the perfect gadget for you. Text Spy can retrieve up any SMS that has been recently deleted from a cellphone - so that could be good if you've accidently deleted the address of the bar you were going to meet your ladyfriend in. For that, I think it's useful. If you think that your ladyfriend has been playing hide the sausage with the pizza delivery boy, then I suppose it's useful too, but you are going down a dangerous road, my friend.

The TextSpy is a professional USB SIM card reader. Install the software provided on the CD onto your PC, plug in the TextSpy with the relevant SIM card inserted and, Shazam-a-lam-a-ding-dong, the last 10 to 20 text messages should show up. But really, guys, at $200, is it worth it? Get your revenge and hit 'em where it hurts: find a new pizza place. – Ad Dugdale
