I have an unlocked T-Mobile 8900 running on AT&T services. I've never had any problems whatsoever and everything works. I'm also running OS 4.6.1.199 and for me, that seems to be the most reliable OS out.
WiFi yes, but I don't believe UMA does. UMA is what allows TMO users to make voice calls over WiFi, similar to VOIP. ATT does not support UMA that I know of.
