Facetime over 3G in iPhone

Now that anyone can easily jailbreak their iPhones (including the latest iPhone 4) with JailbreakMe, it was just a matter of installing the right hacks in order to make Facetime videocalls over 3G (officially you can only do it over WiFi.)

All you need is My3G, a small App that tricks your iPhone into thinking it's connected over WiFi even when it's on 3G. (And allowing you to use your unlimited 3G data plan to its fullest: downloading 20MB+ Apps over 3G, and watch high-quality YouTube videos - things you can only currently do over WiFi.)
