I haven't seen anyone recommend this, but I love Speck cases. Specifically, their Candyshell case. That is all I have been using on my 4S, with no screen protector. This is the one I use. And I will definitely get one for the iPhone 5.

I agree. I just preordered the iphone5 and intend to trade my 4S in so at worst the new phone will not cost me anything since the 4s is in perfect condition.
However, just this morning, while on the elliptical at my gym, the 4s fell down to the floor
with no damage thanks to the and ghost armor
I had better be more careful in the next few weeks as I was shut out of the first delivery of the preorders. LOL.
The only negative of the speck is that I have to remove the case to attach certain cables such as the HDMI accessory.
