3G Echo. When I call people over a 3G connection, they hear an echo. But, over Edge, they don't and the call is clear. I'd like to see a way to automatically use Edge for calls and 3G for data. I understand that I can manually turn 3G on and off, but this seems like it would be easy to add a "network preference" option for phone use. It's just software, you can make it do anything. Wish 2074
