this started about a week ago. my initial thought was the battery so i brought a new one and fitted it (i am a fairly good electrician and techy afterall). however this didnt fix the issue. i did a little research and a few people were saying that they were having this trouble with ios 5.0.1 and that upgrading to ios 5.1 seemed to fix it, so i tried that but it seemed to make it worse. the phone starts up and i can use it for about a minute or 2 but then it turns itself off and back on again. i'v tried a number of different things like cleaning the power button, fully restoring it, but nothing seems to work. its an iphone 3gs btw.
any ideas what it could be? or how i can fix it?
