Great news for the VoIP world: iCall, the maker of the iCall VoIP iPhone app that can catch a GSM call and flip it over to WiFi, has issued a press release saying that the new iPhone SDK allows for VoIP over 3G cellular connections. Previously such calls had to be made over WiFi, since AT&T's network (or someone well acquainted with AT&T's network) didn't think it was man enough to take the VoIP traffic. Interestingly, iCall says its 3G-friendly VoIP app is available now, and is the first and only such app in the App Store -- which seems like some pretty quick turnaround on everyone's part,
