Say you’re sick of AT&T. Assuming you’ve jailbroken your iPhone 4, you can now bounce between two cell networks of your choice courtesy of this unusual case.
The iPhone 4 Dual SIM Adapter case comes with a ribbon cable that pops into your iPhone’s SIM slot, splitting it into two card slots. Then, snap the clear case around your phone to keep the SIM cards neat and tidy. According to the instructions, you just need to go into the phone settings and choose the SIM of your choice and wait 1 to 2 minutes for the network to connect. That’s it.
You can get your hands on the iPhone 4 Dual SIM Adapter case over at USBfever for $28.99 (USD).
