I recently acquired an IPhone 3g with 2.2.1. I ended up jailbreaking with QuickPwn and attempted to install yellowsn0w to allow use with T-Mobile. Well, it turns out the yellowsn0w website is gone. What is with that? I thought the next best option would to just be to reset all settings, well, I accidentally selected reset all settings and data. I was hoping to upgrade to a 3.x version in order to use an updated unlocking method. So, as a result, my Iphone 3g is no longer registering that it is tethered to the computer in any way. It is just booting up the apple logo and restarting every couple minutes. Please tell me I didn't just brick my IPhone. Please help me. I am usually more cautious about these things and have managed to grasp ahold of linux programs like backtrack and use them effectively. I don't know what got into me, I guess I was just excited to have an Iphone 3g.
