I've just completed this very easy mod, I own a tilt which I use in Australia on the 3 network but had no front camera, I got the complete screen off a damaged Tytn II, pulled it all apart fitted the camera and front panel and the lower buttons, now mine looks like a Tytn II with a tilt Keyboard.
so in short it is an easy mod, getting the screen apart and back together is about the hardest part
