I got an Eris a few days ago and everything was working fine till I tried to make a call. The call connected and i had about 4 bars but there was no sound, so I hung up. Then that person tried to call back so I hit accept and all I got was a broken up voice, still with 4 bars. I then got a voice mail so I called my voicemail it connected but still no sound just a slight poping noice every now and then. Anyone have any ideas? This has been happening before and after going to 2.1. Internet works fine, text messaging works fine, and email works fine.
