That’s right. Apple has lifted the restrictions for developers so that they can write VOIP apps that work over AT&T’s 3G network. Back in October, AT&T lifted the restriction on their network and informed Apple and the FCC about it.
Yesterday, Apple released a new SDK for the iPhone and the new iPad. In this SDK, the restriction has been lifted. iCall has already updated their iPhone app, and many others will soon follow no doubt.
I’ll be curious to watch and see how much (or even if) AT&T complains about this extra data usage on their network.
