Now you can change your iPhone’s service provider on the fly, thanks to the Dual Sim Adapter Case. This iPhone 4 case comes with a dual SIM card adapter, letting you switch networks whenever you see fit.
The Dual Sim Adapter Case is surprisingly simple to use. You just slip it onto your iPhone 4 with both SIM cards inserted, and you can then switch between cards via your phone’s settings menu. This case only works for jail-broken iPhones, and it isn’t guaranteed to sync with all service providers. The iPhone is free at last, free at last.
