Anyway, here's the deal. The case is, as I said, designed so you can take a picture of someone or something without having to hold your phone in that awkward position where everyone knows you're taking a picture (or video, I suppose). If you're old enough to remember Brownie cameras, that's how this works, essentially. You point your phone at the ground or to the side, and a mirror in the case allows you to take a picture of whatever is in front of you. You will need a proprietary app installed to make it work for real, but then what doesn't require an app these days?
One of the drawbacks here is if you're trying to be sneaky about taking a picture, you're probably not going to get your framing quite right unless you also stare at your phone's screen. On the other hand, since most people spend the majority of their time staring at their phones anyway that might not be as big a problem as I think. It might even make it easier to capture your images, now that I think about it. One definite advantage is its shape, which will make it easier to keep your phone on your shoulder if you need to do something with your hands while talking and don't have a headset.
The Mirror Case is compatible only with iPhone 4 and 4S, and will cost you $50.00 US.
