My iPhone 3gs has been misbehaving lately:
- Randomly drops signal to "No Service"
- "No SIM" issues
- Restarts itself
- Says it needs to be restored
I have already tried restoring it, cleaning the SIM card, and it continues to restart itself. Help!
It's likely a hardware issue, but it's possible there's a corrupted setting causing this (although it seems unlikely).
When you restored it, did you do so from a backup, or a fresh install of iOS, without transferring your old settings over? Try a fresh restore and see if that fixes the issue — that's the only software problem I can think of that might cause this. However my gut says it's likely a hardware issue, and you're going to need a trip to an Apple store or third party repair centre.
