New to the forums. I bought an iphone 4 from Amazon. It includede a Gevey Sim. Cydia was already installed and jailbroken when the phone came to me. I looked at the info before I started anything but dont remember the baseband...its was 04.(11 or 12) and .01 i think. the iOs was 5.0.1. I was following directions from a video online and it said turn off the phone with the gevey/tmobile sim in it. I did that and restarted..and its stuck on the apple logo now...any thoughts? im at work with no Itunes. and I ahvent even hooked it up to iTunes since i got it at work shipped by the mail and just opened it here.
