This was wierd. I had my berry in my pocket while I was washing my truck and the next thing I know, I start hearing this faint high piched tone.
I thought it was something coming from under my dashboard at first till the sound followed me into the house.
My 8800 had froze up with the sound of I guess one of the # tones on the phone. I missed 3 calls while it was locked up. I had to do a battery pull to unlock it and stop the tone.
I didn't get it wet either. I'm guess maybe I leaned up against it some way.
