im having the same problem since 5 months back.. only way to get it back of respond is to apply pressure on the left side of d HOME button..js like what Andrew mentioned.. but this just a temporary solution.. it will be back after a week or days.. and it's hard to stimulate problem if to send back to claim warranty.. i tried to claim warranty at KLCC.. they said is software issue..n asked to do restore n test first.. i have restored my iphone 4 twice n test but problem still ON and OFF... what can I do so they give a damn on this..??
