Fixed broken screen on iPhone 3g for my 2 kids
My two boys use an old iPhone 3g for games. It got dropped and the screen broke.
Everything went smoothly except the removal of the glass screen from the metal frame. The video for the Front Panel installation stops before showing how to remove the glass. I had to look up another video (not from iFixit site) which showed you how to use a hair dryer to loosen the adhesive between the frame and glass.
But overall it was good experience and I fixed the screen and added a new battery while I was in there. All for about $60.
I would pay the little extra and get the whole front panel, not just the glass screen. The last step of separating the glass from the frame was far and away the most difficult and uncertain. If I simply had to install a new frame (with home button, etc), it would have been much more simple.
