I suspect that an unlock for OTB 1.1.2 is not gonna come for a long time (if it ever does). So, feeling naked without my iPhone, I took the plunge: bought myself TurboSIM for $199 Australian + $15 shipping. It was a bit of a challenge to cut both the original AT&T SIM and my SIM with a knife, but today I am a happy owner of a working OTB 1.1.2!
I also hear that TSIM'd iPhones are not susceptible to firmware upgrades. If that's true, then that's icing on the cake.
If anyone has any questions, fire away.

Sorry I don't have time to post pics, but if you check some eBay listings, you'll see that there is an extra chip on the TurboSIM - I assume to "emulate" an AT&T SIM. In order for your non-AT&T SIM to fit, you'll have to cut out a 9mm x 10mm area of your SIM. The TurboSIM and your SIM line up and make contact, and the TurboSIM acts as a bridge between your SIM and the iPhone. Sorry, but that's the best way I can explain it.
In a nutshell, the process goes like this:
1. perform the surgery (cutting out the 9 x 10 area) on both the original AT&T and your SIM
2. follow this simple guide posted on hackint0sh. As you can see there, you install and run Applesaft on the iPhone. I added a suggestion (correction?) on that thread, too: post #50 on page 5.
The whole process took me less than an hour.
It cost me dearly, but this Christmas, I have a fully working OTB 1.1.2 iPhone!

I have my T-Mo SIM in my iPhone and it works without cutting anything.
You do have me on the OTA an upgrade without bricking the phone.
I am still 1.0.2 because I dont want to have to unlock this puppy again anySIM...
I dont see why you needed to cut anything???

n0m0n, just as the thread says, this is for an OTB 1.1.2 iPhone, a different beast from your 1.0.2. An OTB 1.1.2 cannot be software-unlocked. The only way to unlock it is thru TurboSIM...and I've heard thru StealthSIM, too.
The SIM needs cutting to fit the TurboSIM tray. Once the two line up, they masquerade as an AT&T SIM.
