I had SBSettings installed as part of my jailbreak and the "3G" off button was still enabled even though I have a CDMA phone. I accidentally hit it today...Didn't realize you could lose ALL cellular coverage if you hit that when on a CDMA iPhone. In any case, I've talk to Verizon and they want me to update my phone. I've tried installed a Carrier Update through iTunes but that didn't change anything. I've done all the fixes of turning Cell Data on and off, etc...Resetting Network Settings. Nothing works!! Any ideas guys?? Any help would be greatly appreciated.
