SIM adapter from iPhone to Nexus 4

Hi all,

I'm the proud carrier of two iPhone 4S', one is work provided and the other is personal. I'm looking to pick up an unlocked Nexus 4 at launch to try something different and for app testing at work. As it be, Apple uses a tiny SIM card while I assume the Nexus 4/Most other phones use a standard size. I've found a number of adapters that have mixed reviews, and I'm wondering if anyone has any suggestions for ones that have worked for them?
