My iphone won't switch on
My iphone won't switch on after I charged it up. It lit up while on charge and 5 mins later when I tried to switch it on there was no life in it at all. A couple of weeks ago I tried to use it and just got a white screen no home screen. It stayed that way for around 24 hours then just started working again, does anyone know what i can do?
iphone, iPhone OS 3.1.3
