The latest version of the iPhone SDK, version 3.2, is bringing VoIP calls over 3G. Previously VoIP calls were limited to WiFi, which meant that you couldn’t make VoIP calls unless you were connected to a wireless access point, something which a lot of people have expressed disappointment in, among other iPhone service limitations that have had us scratching our heads.
Why Apple has now enabled this featue is beyond me. Maybe they’re finally listening to their customers and doing something about it. It’s certainly no secret that the VoIP technology over 3G has been here for sometime. For obvious financial reasons, carriers and handset makers don’t want VoIP to disrupt their current calling plan revenue stream. However, with the right business strategy, VoIP calling functionality on cell phones could be huge, making world calling a reality for many, and profitability for all carriers.

Hopefully the new iPhone SDK 3.2 means that the VoIP function over 3G will also be available on the Apple iPad, as it has a built in microphone and speaker so you could still use it for VoIP calls. (www.iphone.com)
