I might be interested if it didn't cost extra.

For example. The wife has a blackberry 8900 wifi
UMA enabled. With t-mobile we didn't have to buy additional gear and
there's no additional monthly charge plus my wife uses so few
minutes they just roll over. Also UMA usage is unlimited, and
does not count against her voice minutes (though other charges, e.g.
international toll charges, can still apply). Uma can also be used
anywhere where there's WIFI. Pretty sweet imo
