I want to begin by thanking all of you for the useful info for the past couple of years. My daughter and I both have had 2G iphones and I've used your site to unlock and jailbrake both. My daughter lost her phone in December and I bought her a 3GS from Craiglist for Christmas as a replacement. However, I'm not sure if I can jailbrake and unlock. We are on T-Mobile so we really need the unlock. I've searched the sticky's and through the forum but I just keep confusing myself. Can her phone be unlocked and what software do I use on a PC.? Iphone 3GS Version 4.1 Modern Firmware- 05.14.02 Thanks!
