Apologize if this has been covered in any threads before, searched but could not find anything. Phone: Iphone 3G, OS 3.0, not jailbroken, not stolen. Have up until today never had a problem with it (bought it december 08). What happened: Earlier today my wife tried to call me. It showed up on the screen and i slid the answer arrow to the right as usuall. For some reason though it was stuck. Phone kept ringing but nada happened. I then held down the sleep button to restart it, only for the whole thing to hang itself. The shut off button is still there but seems i can't effect it. The home, sleep and sound buttons all still seem to work. Is there a hard reboot possibility or what need i do?
