Blue Flash 

We haven't seen much of the Curve 8520 lately, but more and more users are picking them up. I've still been playing with mine and I got in the mood for some cool themes to play around with. With a little browsing I came across the very cool Blue Flash (and its sister Pink Flash). These are basic themes that are great if you are looking to just change things up a bit. Both have their own color schemes (blue and pink obviously) and custom icons. There is a hidden today screen, and the home icons are totally customizable. At only $0.99, you really can't go wrong. Check them both out in the CrackBerry App Store.
