A iPhone Case.

I think leather & silicone case can protect your iPhone very well, but they are all a little bulky, of course you can find a light one, actually, if you don't mind the plastic case, it's also a good choice, like this one http://dx.com/...red-184984, it's easy to take and put into the pocket, I think most of us use plastic case, is the best!

Speck case, I got one from iCase-Zone, it is very good.
