Following close on the heels of Verizon’s announcement earlier this week that future handsets powered by Google Android would support Google Voice, rival American wireless provider AT&T released the news yesterday that they would allow Voice Over IP applications to operate on the iPhone on both 2G and 3G networks; the only VOIP apps currently permitted are those that utilize WiFi. The news also comes following concern expressed by the FCC over the banning of such apps by both AT&T and iPhone maker Apple.

iPhone is an innovative device that dramatically changed the game in wireless when it was introduced just two years ago. Today’s decision was made after evaluating our customers’ expectations and use of the device compared to dozens of others we offer.

While there was no mention of Google Voice specifically, you have to think that the popular voice mail app will be compatible with AT&T’s release of the iPhone.
