Ok, when i saw that the ios 5 gm had been released i got so excited that i downloaded it and upgraded my iphone 4 with it on the spot. It was just after i booted the iphone 4 with iOS 5 that i realised that i was using gevey sim, and that gevey sim might not work in iOS 5 ;( And surley it diden´t. I´t doesn´t work because i can´t get trough the f´in setup process. It asks me to write my pin code and i do it and after that the usual "accept" or "decline" thing shows up and i click accept wait 15 secounds, call 112 for 2 seconds, but after that i´m not able to put my device in airplane mode. the iphone shows this message "you are using sim card from an unsupported carrier" and i can´t get trough the signup process. Is there any way i can unlock my iphone or downgrade to ios 4 or anything like that? or am i screwed? And no i didn´t backup shsh blobs, whatever that is. I´ve read that snowbreez´s new jailbreak is supposed to preserve baseband which makes it possible to unlock with gevy sim, but im not sure. Anybody got any suggestions?
