upgraded unlocked 3GS to 5 and could not activate. Had to get it unlocked again and downgraded to 4.1 to activate. Works on WiFi but no phone service? Any suggestions?
Sounds like you have a hacked iphone, which cannot be discussed here.
Yes. Definitely a hacked phone. And before you insist it wasn't, the act of downgrading from 5 to 4.1 invalidated any warranty and forfeited your ability to get support here or from Apple.
