I have a 4S on Verizon, recently jailbroken. Have had no problems with the jailbreak until now. I was playing around with SBSettings, adding some toggles to notification center and I switched on airplane mode then switched it off. Upon turning airplane mode off, I noticed that my phone no longer showed my carrier bars or 3G status, just my carrier name. Sure enough, I can't make calls (they instantly fail) and my internet does not work. WiFi, however, does work. It's almost like I'm stuck in airplane mode with no reception or data. I've confirmed in settings that 3G is enabled. When I go to settings/general/about it shows Network as "not available." My wife has a jailbroken 4 on Verizon, and her phone works fine, so it's not a network issue. I'm going to try a restore, but the firmware says it will take 7 hours to download. Anyone have any clue what might be going on?
