Hmm.. UMA started working last night all of a sudden. It's the second day since I loaded 22.214.171.1241. Maybe UMA was down the first day I had it setup.

I just had a nice test of UMA with the 8900 and this release: I'm snowed in NJ today and had to host a meeting in NYC. Used a conference line and tried to call in via Verizon (land line via FIOS) -- but got an "all circuits are busy" message. So I called in from my 8900 instead, using UMA.
I wound up hosting a 1 hour meeting using the 8900's speaker phone, connected over UMA through the T-Mobile-provided Linksys router that comes with T-Mobile@Home service. The connection was superb: excellent sound quality -- sounded corded, and not a single hiccup during the 1 hour UMA call. I also continue to find that UMA / Wi-Fi seems to connect almost instantly with this release.
I'd suggest that your problem isn't with the OS release itself, but instead perhaps with settings that may have defaulted to something you need to change with this release.
