We don't follow Android as closely as we probably should so this is news to us. Today's USA Today says that Google is using an entirely different VoiP neutering strategy at the behest of T-Mobile. AT&T forbids Apple from allowing VoIP applications from running on their network.
Apple does allow VoIP applications over Wifi (or at least they had until Google Voice came along), esentially because AT&T doesn't control any part of that ecosystem. For instance, should Apple kill Google Voice functionality on the iPod touch because AT&T doesn't want it on the iPhone?
Strangely, Tmobile/other carriers are forcing Google's Android to take an entirely different approach. Instead of allowing full Skype VoIP access on Android, they are only allowing Skype Lite to work on the device. Skype Lite works a bit like Google Voice - which requires Skype to go over Tmobile's voice line - which incurs voice minutes
