The new iPhone 4 comes with a video calling service called FaceTime. But as most Apple customers may already know, this service works only over the Wi-Fi networks and does not work over the carrier’s 3G service. That’s pretty sad since you cannot liberally video chat on the move since your movement may have to be restricted inside the Wi-Fi coverage areas.
Now, if you are desperately looking for a solution, I would suggest alternate video chat apps like Fring. But if you do not mind jailbreaking your iPhone to get things done, here is an easier option. Cydia app My3G has now released an updated version of their iPhone application that works over the newly launched iPhone 4. The application is available at a price of $3.99 – a small price to pay to enable FaceTime on 3G.
But please do note the risks involved in jailbreaking your iPhone. If you are scared of voiding your warranty or slowing your iOS, then probably it’s a good idea to not jailbreak your iDevice.
