switching between WIFI and EVDO

[yawningslug]

Got my Mogul two days ago. Just got the GPS working. I found one problem with Google Maps. If the wifi is enabled and a network pops up, the phone will try to connect even though I did not ask it. Afterwards, the map loading stops working. It kept saying something like "you don't have data connection...winnetError[0]"Even though I have good coverage with EVDO. ( I do have unlimited data plan). Turn off wifi, can not recover either except a reboot.

I think this phone has problem with smoothly transitioning between wifi and EVDO. Can somebody share your experience of switching between wifi and EVDO? Is there a way to provision the connection? Let's say if the wifi drops, the EVDO will pick up automaticaly?
