Thought I'd share my repair as I just finished it and all appears to be functioning properly.
I dropped mine in a bar. Fell a couple feet onto a tile floor and shattered. I first took back to Radio Shack but having not purchased insurance weeks earlier, I was told I was SOL. This, after the guy behind the counter starts picking away at the shattered glass and pulling little pieces out, DUDE, WHAT THE *(&^ ARE YOU DOING! The phone works and I want to use that thing you know. I think I just managed to grab it back before he pulled a big chunk off in the upper right corner by the logo, behind which happens to exist a tiny little motion chip (I suspect), more on that later.
Next I tried the AT&T store, but got the same result. They could offer me a go phone but that it. Finally, after about an hour with the store rep and about ready to storm out, he finally revels to me that you can buy replacement digitizers on-line. Now you tell me? And that brought me to this forum.
Read the threads and ordered one from Hong Kong for $40 thinking I could handle the wait. Little did I know it was going to be an excruciating 3 weeks for it to arrive. In the meantime, every time I placed or accepted a call, the screen would go blank and I would have to pull the phone apart to remove the battery to hang up. I now think this was due to me having to apply a small amount of epoxy in that damaged corner to prevent more bits of glass from coming loose, inadvertently immobilizing that little motion chip I mentioned earlier. Needless to say, pulling the battery and restarting the phone 3-6 times a day... if I didn't know what frustration was before, I do now.
Today, the screen finally arrives and I am eager to get to it. Little did I know how involved the repair process was going to be. But, struggle through I did managing to not loose that tiny chip under the logo now embedded in epoxy, which at first I mistook for a bit of the cracked screen. Here are a few words of encouragement.
1. Make sure you keep you kids in another room. There are some tiny bits to manage and you don't want little hands anywhere near you with words like "cool what's that dad?" emanating from them as tiny hands creep into your concentrated vision.
2. Take it slow. The video tear-down is rehearsed and parts loosened before removal. It takes more than a fair amount of prying to get the screen off the digitizer and anywhere there is tacky tape, you'll need some substantial pressure. Don't try to cut it apart either. If you go slow, the sticky tape will remain intact. You may have to pull some of it it off the back of the cracked digitizer and put it back on the edge of the screen, but with care you won't need to replace any adhesive. Envision yourself pulling off a label from cardboard. Go slow and it all comes off clean, go fast and you have a mess.
3. Additional tools: Try to find a pair of jewelers magnifiers, or a headset with lights, or something. My eyesight is pretty good, still 20/20, but I struggled to see what I was doing a couple times because of poor lighting. You will also need a MINUTE Phillips screwdriver. I have a micro set, but even the phillips in that set was too big. I had to use the tiny standard head to unscrew those microscopic buggers. For some prying I ended up using a dulled Exacto blade, carefully!!!!, since that little piece of plastic "pry tool" broke almost right away.
4. I managed the repair following the video where the metal plate is pried up to unseat the cable by lifting the metal plate and propping it with the screwdriver so I could see under the plate. Using an Exacto blade, I maneuvered the cable in place to seat it, very carefully. It can be done, but if there's another way as mentioned in this thread, you might want to follow that instruction.
5. Keep the plastic protective sheet on the digitizer just until you are ready to stick it back on the screen. Before that step, hold the screen up to the light to look for fingerprints you've left behind as you were reefing on the case to get things apart. There will probably be some there. Wipe odd with lint-free cloth (read hem of T-shirt) and then slowly remove the protective plastic, carefully line up the pieces and slowly stick together so you can tweak the edge insuring a complete black periphery. Misalign it and you'll be dealing with the aforementioned "glows"
5. For the love of Buddha, FIND A PROTECTIVE CASE immediately after your repair! You won't want to repeat this process, even again.
