The Callet’s Callet for iPhone 4 ($20) isn’t the first case we’ve seen that’s designed to include wallet functionality, and it’s not the best, but this silicone case may work for times when you want one less thing to occupy space in your pocket or bag. Callet’s soft design allows it to easily wrap around the body of the phone; this means it can be pulled off without much force as well.
Cutouts allow for access to all of the ports and buttons, and even the micro-SIM slot on the side. Verizon iPhone 4 and all iPhone 4S users will find that this case isn’t designed for them, and that the side switch will be partially covered.
The defining feature, though, are the two slots on the back. They’re each sized to fit either a credit card or some cash.
