anyone else have this problem: losing function of main control button which changes the applications/functions? when i turn off the phone and reboot, i now only get the phone pad. the local mac dealer said i got it wet and it has rusted out the connection for the power recharger. i don't remember ever getting the phone wet/spilling anything/it just stopped working. of course, now the warranty says no coverage. rats. the phone is less than a year old. suggestions please. thanks.
