I just paired my Nextel Blackberry 7520 with the TL and there was an echo every time I said something. Has anyone else had this problem and how did you fix it?

 

I have the same problem. Does anyone know how to fix?

 

What version software is on your 7520? You can check by going to "Options" and "About". I've had good luck with version 4.0.2, but they just released version 4.1. Both versions should offer improved performance if you're running 4.0.0.160 or 4.0.0.249.

You should be able to download the update direct from Nextel http://www.nextel.com/blackberry and install through your desktop manager application loader.
