hey so i have the 8220 and i got it so i could use UMA...
from my knowledge, with these phones, dont you just connect to wi-fi and change some of the setting to wi-fi preferred?
ive done this but still have yet to see the UMW symbol on top of my BB
So you don't get any UMA symbol? Are you certain you are connected fully to a network? Wifi logo should be b/w and it should say the name of the network next to your carrier.
