[Skunkworks] iPad2 Microsim

Hello Skunks, I just bought an iPad2 from Europe and I was wondering if anyone may know where I can purchase a microSIM card to use with the device. I want a microSIM that can be used on the Safaricom network. Any assstance would be greatly appreciated.   Allan Ouma P.O. Box 12731 Nairobi 00400 Kenya
