I'm happy with it. I haven't noticed much of anything different (in the hour or two on a holiday that I've used it
) UMA still switches to EDGE, seemingly, too soon but maybe it needs to do that to handoff the call to EDGE properly. However, it seems like it changes back to UMA quicker from EDGE. It seems like a fairly stable build. I'll report back if I notice anything but today isn't a day when I use my BB that hard.
