About ScreenSplitr
ScreenSplitr is an iPhone app that mirrors your iPhone screen on a TV or a computer.
Instructions:
1. Install ScreenSplitr via Cydia
2. Start ScreenSplitr
3. Connect an AV cable (I only tried Component so far)
4. The app will return to the Springboard and ScreenSplitr icon should have a “On” badge.
5. The TV should show what’s on your iPhone.
To stop, simply run ScreenSplitr again.
Update:
Check DemoGod for mirroring the iPhone onto a Computer over WiFi.
Update 2:
