We've seen some awesome iPhone costumes, but this iPhone 4 costume takes the cake. It's wicked. The screen looks nice compared to some of the other costumes we've seen, and it's not quite as bulky as the others.
He uses the iPhone 4 to control what's displayed on the screen and it looks very awesome. We are actually intimidated by his coolness.
If this is a little too high-tech and expensive (which it probably is) why not check out these Angry Birds costumes?
