New day, new update in Cydia store: FaceBreak. This tweak is very simple to use and allows you to make FaceTime calls over 3G. Once installed on your iPhone all you need to do is to reboot your iPhone, and that’s it. The new update adds support for iOS 4.1
If for some reason after a reboot FaceTime refuses to connect, just resping by Disabling and then Enabling FaceBreak inside the Settings Menu ( under FaceBreak ). Anyhow, you can avoid that by waiting 1 minute and then retry. FaceTime can be enabled/disabled from the iPhone Settings under ‘FaceBreak’.
Available for $1.49 on the Cydia Store
