The Jail break app was an aHa moment to me and I am sure many iPhone 4 handsets are ready for some further experimentation. One of the most appealing feature in the new iPhone is the FaceTime feature which typically runs on Wi-Fi. But the FaceTime application can now on 3G connection too. This is possible by virtue of Cydia app called My3G a unique application which is built to make Wi-Fi apps run on 3G. So if you Jailbreak your iPhone 4 and install your app then you need not wander around for those feeble Wi-Fi signals. However the video quality again depends upon strength of 3G connection and the video quality sometimes may not be as much you expect it to be.
