So I've had a G1 for a while now and all of a sudden whenever I call people or they call me, I can't hear them talking. They can hear everything I say but I can't hear them. It's never happened before and I went to the Tmobile store and they were no use, other than giving me a number to call to see if I had a warranty still. Anyway, anyone know how to fix it? If I put it on speakerphone it will work, but I can't be on speaker all the time, I'd annoy the hell out of everyone.
