Device: iphone 4 GSM ios: 5.1.1 (9B206) custom firmware Jailbreak: Redsn0w 0.9.14b2 Unlock: Ultrsn0w Hi I just updated my iphone 4 to ios 5.1.1 using custom firmware and unlocking with ultrasn0w. first I tried updating to 5.1.1 (9B208) but kept getting errors 14 & 1602, so I tried ios 5.1.1 (9B206) and was able to restore jailbreak and unlock. Since upgrading I have not been able to send imessages or make facetime calls, when I try activating it just hangs and doesnt activate. I have tried reseting my network as mentioned in another thread but it didnt help, I have also restored about 3x's and that hasnt helped either. Does someone know why I cant activate imessage & facetime, I really need help please. I dont know if this helps but sometimes I have to turn airport mode on and off for my iphone to recognise my phone number in phone setting. and I am able to download from the appstore, so my apple id is OK. Thanks in advance.
