When you can fit a device in your pocket that makes phone calls, plays MP3s and connects to the internet, is it really that much to ask for it to also store your cash and credit cards? No one likes to carry around a bunch of stuff in their pockets, but unless you’re into carrying a man-purse, that’s how it is. But it doesn’t have to be that way. You can cut back to just carrying your iPhone and your keys thanks to iPhone 3G ID Credit Card Cases. The case protects your phone and features an extra slot for some cash, your ID or credit card.
