My iPhone is sick! When I push to home, scroll unlock, it show error:

"This accessory is not made to
work with iPhone.
Would you like to turn on Airplane
mode to reduce audio interference?
You will not be able to make or
receive calls"


If I select "No", it has no sound for speaker when run iPod, get SMS, push keys on phone, etc. (with headset, sound is OK).
But incoming call still has ring sound.

I had to downgrade, upgrade to/from 102/111/112. Same problem. Some time, it works for an hour when it charged full battery. After that, same problem.

Anybody get the same like me? Any ideas?
