Wifi/VOIP i.e. UMA

Hey everyone,

I am wondering if the M8 will allow for hotswapping between wifi networks (support UMA). I ask because I have been looking into getting T-Mobile's Hotspot@Home service and I really want the M8 so if it could allow me to connect to a wifi network and use it to make my phone calls without accruing any mins. then this would be an even cooler product.

I don't think anyone knows at this point.
