My spouse got an iPhone 4 recently and we want to use the old iPhone 3GS as an iPod for the daughter. They switched him over at the AT&T store so I don't know if the old phone has a SIM card in it or not right this minute (not at home).
The WIFI works fine. On the top left of the screen where it would show bars and "AT&T", it displays NO SERVICE.
The issue is this: the battery drains over night when it is asleep. I have charged it the last few days and the next time the kid wants it, the battery is dead. The iphone was only 1 year old so the battery shouldn't be fading.
Is the phone searching for service and draining the battery even when asleep?
I have disabled the location services and made sure push notifications are set to manual or disabled.
Thanks in advance.
