Wonder if anyone can help - my IPhone was playing up so I swtiched it off and then back on and all that happens is the little apple picture appears and then it switches back off. Is it a goner?
Yes it's charged - it started acting weird (giving me the weather in New York when I asked for Hereford, etc) - I've recently had it unlocked, wonder if that has killed it?
in the instructions which you can access online at the apple website, there is how to do soft and hard resets on your phone, its worth a try. mine plays up from time to time because I leave it switched on for weeks at a time, a reset has always sorted it so far. have it plugged in to charge when you do it, the battery may be extremely low
while you have it plugged into to itunes, click on the "help" tab at the top and click "run diagnostics" also make sure you have done the recent update 4.0.2
Plug the phone in the computer then hold down the home button and top button for 10 to 12 seconds, then release the top button. When the computer detects your phone it should come on.
Right, I've done that but it says it cannot detect an IPhone (although when I plugged the phone into the computer it lit up, the apple appeared and then disappeared).
