EVDO on US Cellular Touch Pro

[ropp29]

I have a US Cellular Touch Pro. Where I used to live US Cellular had no EVDO service, just 1X. Now I live in a roaming area, where my phone uses Verizon's network. Verizon has EVDO here, but my phone won't automatically use it.

I can force it by setting "Mode of Operation" (in phone settings; some ROMs require a registry hack to access this setting) to "EVDO only," and then it uses Verizon's EVDO just fine. But when it's on this setting it can't automatically switch back to 1X for incoming calls or texts, which makes this setting pretty useless.

So does anyone know of a way to make the phone automatically use Verizon's EVDO?
