As an early adopter, I just got a BlackBerry 8320 from T-Mobile, which does UMA, so you can use the phone over WiFi. Works awesome with wireless routers that do WMM, basically doesn't work with my AirPort Extreme... As you might imagine, this is quite frustrating, as I have particular desire to have two APs, for basically no reason!
