I haven't ordered an iPhone 4 yet. I'm waiting for an iPhone 5. But I just learned about the Universal Sport Rugged Pouch case for the iPhone 4 and thought some of you who are buying the 4 might be interested.
What I like about it is:
#1 - It's Ballistic. Their products are always well made.
#2 I like the fold-over belt clip. That is really unique. It's handy, achieves the purpose and still looks great.
