I just read a bit of news that will make a lot of iPhone users unhappy. Apple has decided to pull all third party Google Voice clients, err, ugm, GV Mobile and VoiceCentral from the AppStore. We know that there is an official Google Voice client coming for the iPhone. Clients for Android and BlackBerry devices have already been released. We still, however, aren’t quite sure why Apple would pull third party GV clients regardless of if an official GV client is coming out or not.
