I followed all the steps in the process to unlock my iphone 1.1.2oob by software method. (geohot)
All the process went fine, i restarted my iphone, i have signal, the iphone recognice my simcard (claro) but when i tried to make a call, entering to the keypad or recents, the iphone comeback to the springboard. And i cant do calls.
sorry for my bad english
