I like the
Switcheasy cases, though as with Otterbox they seem a bit slow getting themselves up to speed for the 4s. The 'Capsule Rebel' and 'Reptile' cases have a tough Lexan frame that protects the back and sides of the phone really well, and all the Switcheasy cases come with a couple of very good screen protectors. I've dropped mine a few times onto solid floors, and they've been generally used in and around building sites without incident. Recommended.
