Microsoft has made a subtle yet significant change to the famous "I Heart Windows Phone" theme which came out just before Windows Phone was released. Before, the icons were in circles but now...they're boxes, there to represent those iconic tiles on the start screen.
As a way to promote that, they made a handful of stickers that fit on the Samsung Focus, giving it a very custom and kinda kewl look to it. Gimmicky? Sure, but we grabbed one just to make our Focus more hip than yours.
Be jelly, it's okay.
