This is driving me nuts, should I take my iPhone to an Applestore? When I leave my iphone in my stand the thing turns off randomly? Sometimes a few mins, maybe an hour. It ONLY happens in the stand. (Conntected and unconnected to my Mac makes no difference) The phone appears to be in standby (Black screen) but it's only when I go to wake it I find it's powered off! This does not happen anywhere else, in my pocket, lying flat on my desk, left overnight flat on my bedroom cabinet. Only when it's in my stand. Phone is currently standard 3.1.3 but the same was happening when it was Jailbroken 3.1.2 and I put it down to that!
