After the March 6th conference Steve asked the media to stay behind for a few minutes for a Q & A session. In it Steve responded to a question asking whether 'VoIP would be allowed to be developed with the SDK?' stating that Apple had no plans to stop development, submission and acceptance of VoIP applications to the App Store as long as they were based through and took advantage of WIFI. Apparently Apple have a contract with AT&T which states that, for the duration of thier contract, Apple cannot introduce conflicting service(s) which would use the EDGE network to operate.
To Quote:
'In a Q&A session after the Apple iPhone Roadmap event on Thursday, Steve Jobs was asked about VOIP applications. Apple will allow them on the W-Fi network. Mr. Jobs and Mr. Schiller answered other questions as well.
"We'll limit them [VOIP apps] over the cellular network but WiFi will be fine," Mr. Jobs said.'
You all heard it from Steve back in March, you just didn't realize it.
