Are you the kind who has to constantly toggle between two networks on your unlocked iPhone 4? USBFever has launched a new adapter case that will make it easy to hop networks with their new Dual SIM adapter case. The case comes with a slot for you to house two SIM cards so that you may no longer worry about dropping or losing your tiny SIMs while on travel.

The dual SIM adapter case is available at a price of $30 and does not require you to cut or modify your SIM card sizes. One thing I am not convinced about is the look. The case, along with the strap to connect the SIM to the phone may not retain the native aesthetic looks on your iPhone. Nevertheless, if you are willing to give it a try, go ahead.
