Two SIM cards is better than one, right? That’s what you can get if you use this innovative iPhone 4 case from Vaveliero. The Italian based site sells an iPhone 4 case that lets you switch between two SIM cards while using your iPhone 4.
The case plugs into the iPhone 4’s micro-SIM try with an external dual-SIM adapter that is then integrated into the iPhone 4 case in order to keep the SIM cards secure and protected.
While the Vaveliero case will allow you to add an extra SIM card to your iPhone, it doesn’t let you use them both simultaneously. Instead you have to switch between the two SIM cards.
The dual-SIM pack costs €49.90 ($70) and an English language PDF that explains the Dual-SIM convertor can be found here.
A video demonstration (in Italian) is below and shows the dual-SIM cover in action.
