I have an 8820 and recently activated the UMA plan. I am getting connected to my home network and get the Wifi signal but the "EDGE" doesnt change to UMA.
Also in teh mobile networ - it doesnt give me the connection preference option.
Yes i do have teh 8820 - i even had teh admin resent the service book from the BES, and even imported teh certificates. Still no UMA. On the WiFi adavanced diagnostics also i do not see a UMA section. I'm stumped - Tmobile is no help on this - they blame it on BB.
This may not be the solution but I've noticed that I will be getting UMA but it doesn't show due to which theme I'm using. This may not be your problem but its something to look for.

I had the same problem with my 8820 from tmobile. When I spoke to the BB specialist I was told if the UMA icon is not there then your not connected to UMA connection which means your using minutes from your bucket.
Where is says EDGE/GPRS it should change to UMA when sucessfully connected.
Trying going to OPTIONS then click MOBILE NETWORK and under CONNECTION PREFERENCE change it to WIFI PREFERRED. Then on NETWORK SELECTION MODE make sure if says AUTOMATIC. This should solve your problem. Changing the option to automatic enable your device to change from EDGE/GPRS to WIFI automatically when is detected. Make sure you click save, and see what happens.
