I got my Blue Arctic Samsung Galaxy S4 on 11/14 (the day Best Buy released the blue color). I actually had a white one, but after hearing that Best Buy was planning on selling the Blue color on 11/14, I went and got my self one. I'm on AT&T though. Although I did purchase it outright, I'm going to have to call AT&T to have it unlocked.
The blue color is very awesome to look at.
