Took me a few tries to get the camera seated properly - if it's not seated correctly, you'll have problems attaching the WiFi antenna. Should sit flat and square.
On reassembly, be really careful when reattaching the digitizer cable - the cable breaks very easily, rendering your nice new display useless. In my case, I must not have threaded the cable through properly, so it was just a bit too short to reach the connector. I gave it a gentle tug... and snap!
I was much more careful the second time through :(
So many little tiny screws! I wasn't sure how I was going to get them all back in their holes, since the screwdrivers that came with the kit weren't magnetized - extremely difficult to accurately place a speck of metal with a fat finger. I attached a decent magnet I had to the shafts of the 3 drivers and left overnight. In the morning my screwdrivers were lightly magnetized. Worked like a charm!
