I think that it never got resolved. When I had that phone, I got a jawbone headset to cancel out all the background noise. I really prefer it now, no matter what phone I'm using. It was one of my un-noted reasons for leaving them as a carrier tho. It was like they did things to the phones to make it annoying to use. I haven't had any complaints on my 8310 or the 8700. And as a matter of fact, I've been using my sisters 8800 for a week now, and it had'nt had any echo or voice spike issues. via BB (wap.pinstack.com)~
