Touch keeps switching between 1x and EV?

[mindfrost82]

I'm in an area with GREAT EV-DO coverage. I've had other phones (Sanyo MM-9000, Fusic, RAZR, 700wx, MotoQ) that never experienced this, and I've only noticed it on the Touch.

Sometimes the data symbol will flash to 1x sometimes, then go back to EV. It doesn't seem to matter how well my signal is. Since it only stays on 1x for a second, I can't test an incoming call or data speeds. It usually happens when the data connection is inactive.

The roaming symbol never appears either.

Anyone else experience this?

I also notice when I'm on a call, it automatically switched to 1x, then when I hang up it goes back to EV.
