OK, I know that the jokes will be fast and furious with this one, but I actually do need help.
I have a friend who has an iPhone 3G (NOT 3GS) on AT&T. I've spoken to her for many years on older phones with no problems. Ever since I got a DROID, she claims that every few minutes there is a very loud piercing beep that comes through her phone from me. I do not hear this beep. No one else that I've spoken to with my phone has this issue. Yet, she continues to insist that it is happening. She does not have this issue with anyone else's phone.
Neither of us are using Bluetooth or Google Voice. This is straight-up cell phone to cell phone conversation.
Does anyone have any ideas as to why this could be happening? I don't want to give up calling this person, but I don't want to give up my DROID either!
