There really should be no argument when I say that a case for your iPhone 4 is nothing short of necessary. Unless you’ve got cash to burn, the iPhone is just too damn expensive to leave unprotected. The only problem is that most of them make your phone pretty clunky, which sucks since Apple works hard to make the iPhone as slim as possible. Unfortunately, the only trade-off for all the heft is protection against impact. But what if you drop your iPhone in the toilet? The folks at Catalyst have an answer for you: EscapeCapsule.
