Couple of things:
1. The install was not too difficult. I am a bit anal retentive, so I took my time applying the stickers and adjusted them a good bit.
2. The stickers have a tendency to deform a bit if you put one on and then take it off to adjust it. The side stickers in particular got a tiny bit longer as a result - which I actually like.
3. I had to use an X-acto knife to open up the hole a bit for the 3 pin connector, probably due to #2.
4. After applying the stickers, my phone felt like it was covered in stickers... which is was. Burnishing down the edges of the stickers with my thumbnail helped greatly. This also helps with the corners if they get a bit crinkly (I think you can see this in one of my pics - I was able to fix this).
Really not a bad install at all. The screen is a bit foggy, but I just installed the screen protector - should go away soon.
