Iphone 4s can't turn off
Hi
Ok I'll describe the whole situation: the phone won't turn off, just simply reboot. Also, usage and standby time are almost the same (maybe 30 minutes difference) even if I don't touch the phone.
I've tried everything: dfu mode, completely discharging the battery, set as new phone...
Some people say it is because the SIM card, but I've tried T-mobile, GiffGaff and no sim card and the problem is still there.
I can turn off the phone if it is plugged to the computer, but the moment I unplug it, it turns on.
Some people say that is a hardware problem (probably the dock), but the phone is out of warranty, so if anybody has any idea what could the problem be... I don't want to spend £40 in a new dock connector.
Cheers!
