I've had my phone for about 2 weeks now and i insta-jailbroke it. I've noticed that in certain locations my phone powers itself down when it is locked or auto-locked and it takes about a minute or so to power back up. At first i thought it was problems with the carrier switching to Orange from T-Mobile so i disabled that and no luck. Also, when its powered itself down, the battery is drained excessively even though it is switched off. Its strange that it only happens when i go to certain places, at home it works fine but if i walk half a mile away it will power down.
What would be the best way about fixing this? should I unjailbreak it and take it back or can Apple tell even if its restored?
If anyone knows a fix that would be even better thanks
