Apple opens up VoIP via 3G on iPhone, and maybe even iPad
AT&T made the changes that would allow iPhone VoIP on its 3G network back in October, so the holdup has presumably been on Apple's end since then. Now that Apple has lifted its restrictions, though, does this mean the iPad with 3G service will be able to pull off VoIP calls? I sure hope so. It would be nice to have just an iPad, instead of carting around an iPhone, too.
If you're impatient for a Skype update, you can test out 3G VoIP with iCall, an alternative app whose developers have been using the news of the new SDK to draw attention to it as the first app to actually enable cellular VoIP call via iPhone. iCall is free, although somewhat crashy and unreliable, and it can fill the void until Skype swoops back in.
