Hi I have a iPhone 2nd Generation (not 3G) and the problem is that when the phone go to stand by (Auto Lock) donīt sound or vibrate (when I hit the home buttom it only appeares the missed call), if the phone is not locked it sounds and vibrate normal. I already install the 2.1 but wasnīt the solution.
Also my WiFi went dead like 3 months ago but I am sure itīs not related with this problem.
