Well I unlocked and jailbreak my Iphone 2.2.1 and I get this message in the top left corner it says no service so i take out the sim and put it back in and I get an endless searching in the top left corner. So i thought restore and rejailbreak and unlcok but now with firmware 2.2 and still same problem. restore and unlocked this thing many many times no luck. Still no luck, hope u guys can help me. My Iphone is on firmware 2.2 unlocked and jailbreoken right now.
