UMA just appeared on my phone, as well. I did all the recommended procedures and hadn't been able to get it to work. I was away from phone for about an hour, just sat down, and there it is, UMA.

so as I'm typing this I look down at screen, and the darn thing says EDGE again. did a wi-fi diagnostics and it shows all green checks for UMA. . now it's back to UMA.. .. now EDGE.. literaly I am typing this close to real time. it's on EDGE (no pun intended) at the moment. working or not, the UMA functio is at best very unstable in .37

However, all of my 3rd party apps are working without a problem : Viigo/Tango WES preview, Facebook, yahoo Aim and win. Live messengers, all work well. I am running this with the free, but very awesome precision Zen them from eveek.com. Still waiting to test the wirless signal out in the open in some areas that .18 just stunk on. anyone else see any improvements here yet?
