Free Skype VoIP 3G calls

You can now use the Skype 2.0 update with the Apple iPhone to make free VoIP calls over your existing phone plan.
This service will be in the iPhone Appstore, that is, until August when Skype have announced that they will start levying a small subscription charge.
That fee will almost certainly be made up for quickly once you can make free Skype to Skype calls across smartphones. With an unlimited monthly or yearly plan available from Skype this new feature could cut down your calling costs massively.
This is in part because the American network operator AT&T have allowed cellular access to their VoIP network.
Although Skype to Skype calls have always been possible, in the past they could only be made using a Wi-Fi connection.
Not only can you save a packet on your calling costs but you can take advantage of faster setup times and crystal clear calling quality.
Unfortunately Skype don't seem to have any plans to do the same for the Windows Phone, so bad luck if you're stuck on that platform :(
