Apple introduced a very cool feature with iPhone 4, the FaceTime video calls. However, it only works over Wi-Fi and blocked to run over 3G. Now it is possible for jailbroken iPhone 4 to run FaceTime over 3G using the new My3G application. The app also enables you to watch high-definition media and run VoIP clients such as Skype over your 3G network.
The features supported by this app includes the ability to select which apps to run on 3G, indication when an application switches from Wi-Fi to 3G, default configurations for most common apps and dynamically switches to Wi-Fi when available to name a few. It is available in Cydia app store for $3.99.
- Jailbreak your iPhone 4 by following the procedure on this guide.
- Open Cydia app store and search for “My3G”.
- My3G will install RockApp as well.
