That's the problem.
I had the 7100g with Cingular and it would make that horrible noise next to ANY speaker! I couldn't place the phone in a cradle in the car unless I completely turned off the radio and I couldn't bring the phone anywhere near my bedroom because the noise would come through the speaker in the alarm clock, baby monitor, you name it!
I now have the Pearl from the T-Mob. I never hear that noise any more. I can leave it right on the night stand next to my alarm clock and nothing.
Sounds like a Cingular issue to me.
