Help! Stuck in Airplane mode

Hi,

My iPhone keeps telling me that "This accessory cannot work with the phone. Do you want to turn on Airplane mode to reduce audio interference? <Yes> <No>"

I've tried to restore to 1.0.2 and downgrade the baseband to 3.14 but still get this error.

anySIM 1.1 says it's unlock successful but I can get mobile signal.

Please help or point me to the resources for remedy.

Thanks so much!

:(

this is usually related to an fm transmitter ... Did u connect ur phone to one recently? Try reattaching and removing one
