Have had my iphone for a few weeks now and ive started to get problems which are very annoying. When im on applications, mainly facebook and zippo(friends like playing with it), the iphone just turns off, it doesnt turn on unless i hold the home buttion and sleep/wake button, but most of the time that doesnt work i have to wait to go home and plug it into itunes before it starts working again. Another problem im having is that when im listneing to music for a long period of time the home button stops working, when i press it nothing happens, and when i hold down the sleep/wake button it doesnt go to the shutdown slide thing. anyone no whats happening? shall i take it apple or 02? many thanks, grant!
