Even if you’re hardy enough to carry Apple’s LiquidMetal-crafted SIM Ejector Tool on a chain around your neck, it’s not exactly an easy chore switching between networks with your iPhone 4.
This remarkably hideous iPhone 4 case, though, could make changing between SIMs a lot easier for road warriors or users with both a work and private cell phone contract. An interface ribbon connects a micro-sim adapter installed in your iPhone 4 to a pair of regularly sized SIM cards installed in the case, which can be switched from the SIM Applications menu… although we would think a jailbreak would be required.
Not exactly the most elegant solution, and it would certainly look a hell of a lot better if the case wasn’t transparent, but if you find yourself doing a lot of traveling abroad, or simply want to be able to use your iPhone 4 with two separate contracts on the same network, this might be $29 well spent.
