The Jailbreak for iOS 4, 4.0.1 opens windows to the world of applications that aren’t there on the Apple store. One such application is My3G which enables FaceChat (face-to-face video chat) over 3G. Apple had capped this service to be used only when you are connected to the network via Wi-Fi, but this new application breaks all barriers and lets you do the same over 3G for a small one time fee of $2.79 from Cydia or $3.99 from RockYourPhone. My3G makes the iPhone OS believe that it’s connected over WIFi, when it’s actually connected via a 3G network.
FaceTime work fine, but the call and video quality depends on At&t’s 3G network, so you might get blips, hiccups and all sorts of frozen videos while on face-to-face call over the 3G network. Fring also allows you to make video calls over 3G, and you can video chat with any non-iPhone user as well. Your phone need not be jailbroken to use Fring (as the application is available in the Apple store), but the person you’re trying to reach much have the Fring application installed on his smartphone.
