With the exception of the new wi-fi Blackberry, TMobile's UMA handsets have a hardtime logging on to non-TMobile handsets. The browsers won't handle wi-fi until the UMA tunnel is established and you can't establish the UMA tunnel until negotiate the wi-fi login.

It is also worth stressing that UMA is not your standard SIP VOIP. A SIP based phone (e.g. the Nokia E Series) won't handle UMA or Vice Versa. The HP Communicator may be able to handle both. That is the only one I know of.
