It seems Apple has one less straw man to throw at investigators over the Google Voice rejection. AT&T has decided, at long last, to allow VoIP calling over 3G connections. VoIP over 3G has been the reason behind a whole slew of app rejections for the iPhone. The change probably comes as a result of the net neutrality discussion, but even so, it’s something I expected AT&T to fight aggressively, not acquiesce to.

The policy change means you can now do some pretty cool stuff, like use Skype anywhere, or the new Vonage app that heralded the VoIP announcement. It also puts a lot of pressure on Apple to push the Google Voice app through. We all know the “duplicating iPhone features,” defense is a load of crap, and this leaves Apple with very little reason for the rejection.

Of course, the policy change also means a lot more data traffic on AT&T’s overtasked network. It’ll be interesting to see how well that holds up.
