I read through different threads about people with dead iphones and only came on when doing the hard reset. If an iPhone is in this dead state should it still be recognised by a computer or display charging screen? Reason i ask is that my iPhone 3GS could have a dodgy power button i had trouble with it for quite a while sometimes it works sometimes it doesn't. This could be a reason why the hard reset will not work for me. At moment i iPhone doesn't get recognised by computer or display any charging screen. Thanks, If the power button is the culprit is there any other way to do hard reset? or fix a power button without opening the case?
