I have a simple question, is there a Gevey sim for iPhone 4 on iOS 5.1.1? Also, does iOS 5 require a different gevey sim from iOS 4? I was previously running 4.3.3 and was using a gevey sim. My iPhone baseband is 4.10.01. I used Sn0wBreeze to upgrade so the baseband was preserved. Also, my sim doesn't work on my old gevey sim tray, it keeps giving me the No Service error. Please help?
