Why is my spray paint still sticky?

I have been trying to successfully spray paint a plastic iPhone case for a week now.

I sanded it, put a clear coat of spray paint specifically made for plastic on it, let that dry, and then I put a few coats of the regular spray paint on it (letting it sit and dry for 30 min to an hour in between coats), and lastly put a clear protective coat on it. It's been sitting for about a day without being handled, and the paint seems dry now. I can tap it with my fingernail and it doesn't leave little marks. The problem is that it still seems a bit sticky. Not like super sticky but enough that I notice it when I pick it up, put it down, and especially when I put it up to my face to answer phonecalls, etc. I was just wondering if someone could tell me what I either did wrong or what I can do to stop this stickiness. It would be GREATLY appreciated, because after a week of trying to get this to work, I'm about ready to pull my hair out.

How to recover photos off an iPhone you no longer have?

My iphone fell into the lake and I have now a new iPhone (4) as a replacement. While at the lake I took a bunch of pictures. Is there anyway to get the pictures I took on my previous iphone to my new iPhone? I had iCloud set up and it recovered up to about a week before the phone was destroyed.
