iPhone 4 FaceTime Over 3G

Those of you who aren't happy using Fring for your 3G voice calling will be glad to know that you can now use Apple's own FaceTime app over your 3G data connection.  It will just require your phone to be jailbroken.  Once you've managed to jailbreak your iPhone 4, an app called My3G will let you video chat outside of those limiting wifi network. Video quality seems to be unaffected, but frame rate is slightly diminished due to the reduced bandwidth; a fair trade for the increased mobility!

Your list of  reason to jailbreak just got a bit bigger!
