Apple Blocks Google Voice

In a move apparently calculated to protect the interests of carrier partner AT&T Inc., Apple Inc. has rejected Google Voice for iPhone.

Google Voice, available by invite only, is essentially a free unified messaging app that allows users to place cheap international calls and free SMS messages by routing them through Google, and to share a single number across phones. It also lets them manage their text and voice messages – including a speech-to-text conversion of incoming voice mail messages. Its arrival on the scene has sparked much speculation as to the threat of Google becoming a full-fledged voice provider.

Not every carrier is concerned: Google Voice is cleared for Android and BlackBerry handsets.
