If there's any device that knows a thing or two about impact, it's the ping-pong paddle. first rubber case for iPhone 4, the ($30), is inspired by a paddle's textured-rubber surface. The injection-molded case securely fits over your phone, while its surface nubs provide extra grip and lend the case a unique, table-tennis aesthetic. Though you may feel the urge to do so, we advise that you abstain from using your Ping Pong Cover-adorned iPhone for actual ping pong games.

The ($28) lives up to its fearsome name by providing multiple layers of protection for your iPhone. A shock-absorbing silicone core provides the initial protective layer, while a rigid polycarbonate frame adds an extra level of sturdiness. Raised ridges allow for increased grip and durability, and a built-in belt-clip holster lets you keep your iPhone within easy reach at all times.

($25), available soon, is a thin, transparent film that protects the front and back of your iPhone 4 from scratches and smudges, while adding virtually no extra bulk. Accurately applying a protective film over your iPhone can be difficult, but Kioky's iPhone 4 Screen Protector comes with an applicator device that the company claims makes it easy to center the film for a precise fit.
