Leaked screen shots of training material for T-Mobile employees shows that UMA, or calling over Wi-Fi, may soon be available for certain Android phones running on the nation's fourth largest carrier. What gives these screen shots the look of validity is an icon that appears on both the training material and on a image we saw this week of the G2.
Unlike the current UMA service, calls can not be handed off which means once you leave an area of coverage, the call you are on will be dropped. The service also will not be made available to all Android handsets. And if the G2 doesn't launch with Wi-Fi calling, don't jump from the highest floor in your building. It could be something that T-Mobile will add in a future software update.
