I have been asking this question and googled for a few hours, but i have not been able to get a response back. I am trying to decide between a BB 9700 and this phone, but leaning to the 9700 for the UMA capabilities. Signal is horrid at my place but i figured i could use wifi, hence me moving away from my 3g iphone. So does the HD2 support UMA calling and texting, etc etc.
HD2 Does not. Currently the only non blackberry phone that does and is still offered by T-mobile is the Nokia E73. It seems that if someone could pull UMA out of the Shadow II's ROM and put it on an HD2 it would work, but so far, no one has.
