At iFixYouri, experiments abound. That penchant for fun got me going with jailbroken WiFi and 3G network settings for Facetime that allows you to have a face-to-face conversation with a loved one anytime, anywhere regardless of your current internet situation.
MyWi is an app that allows you to use your iPhone as a wireless router but without the pesky wires. My3G tricks your phone into thinking it is on a wireless network when it’s actually using your 3G connection. It allows you to use Facetime on 3G networkw and is brought to you by the same people that brought you MyWi.
