So I tried to do too much at once with a 7month old in one arm and a handful of stuff (and my iPhone 3Gs) in the other. The phone slipped and tumbled to the screen's demise. Naturally I turned here to get parts and "how to" instructions.
The repair was great. It was my first time so I had some nerves to calm and some apprehension too. The instructions were great and the parts were perfect.
The only suggestion I would make is to have even more depth with detailing where the ribbon from the new part should be "tucked" or pushed when adhering it to the existing plastic structure of the iPhone. There were warnings of where the ribbon should go but I still had trouble cyphering the instructions and pictures. The next handful of steps made it obvious how I should have completed that step. Overall ... very happy!
