The only way to remedy the problem for me is to power down and pull the battery, even a Cap+Alt+Del doesn't bring the radio back.
To fixed that problem. Turn off wifi and then the GSM radio, wait a few secs, then just turn on the GSM connection then turn on the wifi connection. I think that the UMA and EDGE are trying to request BB services at the same time and takes a long time for the BB servers to realize its two different request and to choose the right one to connect to.....
It should choose exactly what your connection preference is but TMO has yet to work the bugs out on that
