The LifeProof iPhone 4 case wants to keep your iPhone safe from just about everything. The company claims that the LifeProof case is waterproof, dirt proof, snow proof, and shock proof. Indeed, in my testing, the case seemed to keep my iPhone safe, but there are limitations to the LifeProof that you should know about before you dive in, so to speak.
The LifeProof doesn’t ship with a manual; instead, you’re directed to the company’s website for text and video instructions on the case’s use. The case itself consists of two polycarbonate shells that snap onto your iPhone on either side. The online manual stresses the importance of assembling the case around your phone patiently, ensuring all of its internal latches lock together. Failure to do so, of course, could negatively impact the case’s ability to keep water and dust particles out.
Snapping the case shut isn’t too tough. You just squeeze tightly, everywhere, and it snaps together. Taking it apart requires a bit more effort, unsurprisingly, and LifeProof emphasizes that you must do so in a seesaw fashion, carefully ensuring that you don’t bend or otherwise damage the shells.
(In truth, LifeProof really doesn’t want you taking the case off too much—it’s designed to be a put-it-on-and-leave-it-there case. The company suggests that you can open and close the case about 50 times before its many latches will become too worn to ensure your device’s protection.)
There are numerous retro iPhone cases on the market, and most of them have no useful features except for helping you to stand out from the crowd. Holga, however, has introduced an iPhone case that not only adds some vintage flair to your smartphone, but also allows for photographic experimentation with nine built-in special effects filters.

Holga is a Chinese company known for its low-cost film cameras, that snap quirky distorted images. The unusual effect is appreciated by a number of professional photographers, even though it’s certainly achievable using photo editing software. With the Holga iPhone Lens Filter Kit, it’s now possible to play with lo-fi effects without a separate lo-fi camera.
