With AT&T’s decision on Tuesday to enable the use of VoIP apps on its network, Apple is moving quickly to make changes for its developers. “We are very happy that AT&T is now supporting VoIP applications,” Apple spokesperson, Natalie Kerris, Told The Loop. “We will be amending our developer agreements to get VoIP apps on the App Store and in customers’ hands as soon as possible.”

There are a number of VoIP apps that could be affected, including apps from Vonage and Skype, but the one everyone is waiting for is Google Voice. Apple would not comment specifically about Google Voice, when asked today.

Google Voice is not technically a VoIP app, but it will be interesting to see how Apple handles the app with the changes today. There’s a very good chance that it will have no effect at all.

Apple and AT&T were asked by the FCC in September why Google Voice was rejected. Apple said the app was never rejected, although Google maintains it was.
