And I brought it back to life. I was using the phone put it down and a second later picked it up to check the time. Pressed the home button, nothing, screen didn't come on. I thought maybe the home button died or something. Pressed the sleep/awake button and still nothing. Before this happened I was down to 16% battery so thought maybe the battery indicator was off and the battery simply died. Popped the phone on to charge and waited a few minutes for it to come on. Nothing, no charging indicator. I thought I'd let it charge overnight and see if it turns on in the morning. Morning came, checked the phone, nothing, dead as a Dodo. I decided to try a reboot by pressing both buttons before I rang Apple. The Apple logo came on and the phone restarted and is working fine atm. What do you guys think? Hardware fault? Software faut? Gremlins? Has this happened to anyone else?
