I have used Otterbox for my iPhone 4 and iPad. Anymore, I don't use the Otterbox for my iPad. The Otterbox makes the screen look like crap.
I'm tempted to start using my iPhone 4 without the Otterbox. I'm really liking it without it.
Otterbox Commuter. Great protection and not bulky. If you wanted more protection, get a LifeProof case. They aren't too awful bulky.
