It could be because the cell sites are not yet equipped to accept the Wifi handoffs. My UMA will take calls fine, it just wont handoff, so this could be the issue.
This also especially sucks, because by the time it's "supposed" to work, my 30 day return period will have expired. Luckily, I'm headed to Vegas next week, so I should be able to try it out somewhere else, where it allegedly works.
