I was so excited to upgrade to 4.1 for the Bluetooth fix...this morning I called my dad and he said he could hear a terrible echo of him self on his end. It sounded like crap on my end too. Then I disconnected the headset to use the iPhone 4 itself and it sounded crystal clear. I have a blueant q1 and an ip4 on 4.1 Any suggestions here guys...should I do a complete restore again? Is anyone else noticing this aswell?
