Is there an app to shut down my iPhone 3G? It's a non jailbroken iPhone and the power button isn't working anymore. So I need to shut it down with an app. Any advice?
Don't know if this will help. I had the same problem with a 3G. I found if you squeeze the front and back of the phone, just at the on/off button whilst pressing the on/off button, then it would all work fine. It's as if there's just a connection that's slightly come apart, which squeezing reconnects. Kept me going for months, as I waited for the 4S! Good luck.
Apps aren't allowed to access this functionality so there is no way to get this without jailbreaking.
Challenge accepted. The best app(lication) for the job would be to let the battery run out. Problem solved. Rejoice!
