Check out a Dual SIM iPhone 4 case!

Today you can find a lot of phones with dual slot for SIM cards, most of them are designed for Asian markets, but the iPhone is far from the two SIM cards: in fact, it does not even sport a Big Person SIM to call its own. Fortunately, USBFever has the perfect solution to this problem. USBFever offers a new case at $ 30, where you can put two SIM cards on the back side of the iPhone 4 (built in a rather stylish, transparent plastic), while the adapter is connected to the micro SIM slot of your iPhone 4. Now you can switch between two SIM cards with your own iPhone’s setup menu, though, unfortunately, you can not use both SIM cards at once.
