Alright. Much like a iPhone 3G/3GS, there's some sticky tape involved. Rather than splitting the glass from the LCD, you'll be pulling all glass, digitizer and lcd out. One tool I recommend for splitting the glue tape, a guitar pick. They actually send those with some of the iPhone screen kits. And grab your spouses hair dryer...
First off, thanks iLoki for the instructions. Removing the back plastic I think was the hardest. Just out of raw fear you'll snap the final upper clip. It pops when you remove it but don't waste a good panic when you hear the sound.
On the final steps of iLoki's instructions, you remove the ribbon cable under the blue tape to remove the speaker assembly. You can skip this step. Just pull the one screw that holds the assembly to the chassis. you can remove the mainboard and speaker in one piece. After that, pull what I assumed is the radio assembly on the bottom of the chassis to avoid snagging anything. It pulls right out after you disconnect the white antenna cable.
When the mainboards out, it's time to unglue. I used a hair dryer rather than a heat gun this time. It worked fine. I used low fan, high heat for about 60 seconds on each side I was working with. Use the guitar pick to start separating the screen from the chassis. You'll see the black tape that runs around the chassis in the picture. Don't worry about destroying that black seal tape. It comes with the screen. I did one side and worked the bottom, top and then the final side. If the glue is stubborn, try some more heat. Use common sense with that.
Once the screens separated, pull the black tape from the chassis. Be careful around the 4 bottom buttons. There's a silver metallic ribbon cable underneath. You'll see it in my picture with the tape rolled back.
The new screen came with 2 seperate sticky tape pieces on the screen. One for the perimeter and one for the main part of the screen. Peel them off and align it for install. Make sure the ribbon cable for the screen goes through the slot on the chassis. To get the screen "squared" up for adhesion, I used the speaker grill for alignment. AKA, start at the top, and lay it down top to bottom.
That's about it. Let me know if you have any questions. I'm around Atlanta so if I can ever help in person, let me know!
