HI there! I upgraded my iPhone 4 to iOS 5.0.1 and jailbreaked and Unlockedit with redsn0w. This iPhone has the 01.59.00 BR. I don't know if this is a problem with Ultrasn0w or where but: I don't get the 3G network working. The 3G network also doesn't allow me to send MMS, broken Voice Mail shortcut, 3G data not working and any service related with it, like: FaceTime, iMesssage, Find my iPhone, etc. Everything else works fine. I changed the SIM card, I reinstalled everything again and nothing happens. I don't know what I'. doing wrong. Any advice?? Cheers
