So I was able to downgrade my phone last night from 4.3.5 to 4.3.3 using Redsnow rc19. But after the jailbreak I have no internet connection. It has full bars and 3G but can't access any network apps or internet. I have already tried resetting network settings, but for some reason everything works on WIFI. Please help!!! I can receive and make phone calls and text messages.
