Hi, I have had my 3g since aug 08 so is out of warranty (didn't get apple care). I use the silence switch often when going in/out of class. Recently the switch will turn to silent but constantly comes in and out of silence. The phone keeps vibrating and the icon on the screen flashing on and off. This can be achieved by even Just touching the switch. This does not happen when silent mode is turned off. Now I know I have no warranty but can this be easily and cheaply fixed?? anyone had the same issue?
