My 3GS keeps having a strange issue, but I think I've found a pattern.
- First let its battery get low enough to where it turns off on its own
- Recharge it enough to come back on
- After coming back on, every 5 minutes the 3GS just reboots randomly
To fix it, the only thing that works is to do a restore from iTunes (which sucks if the backup is kind of old)
It is out of warranty, has anyone had this issue? Would a new battery help? I'm also wondering if jailbreaking it might help to where there is something I can do command line to fix it (I'm proficient with Linux/SSH).
My wife uses this phone, and it's hard to get her to keep it charged. I'm running iOS 5.0.1.
