The iPhone does an amazing job at sharing, displaying and editing your pictures, but not so much at actually taking them. Well, here is an accessory that should let you connect the best of both worlds, zoomIT's iPhone SD card reader.
It connects itself to your iPhone dock connector and thanks to a dedicated app, it will let you transfer pictures between the card and your iPhone's camera roll.
It's a little pricey ($60) for something that isn't worth more than a couple dollars, but unless Apple's official iPad SD card reader works on iPhones, we might have no other choice and this definitely looks to me like something I want.
It's available in preorder now and should hit the market in about two months.
