Purchase Factory Unlocked iPhone

I've been in the market for quite sometime now looking to purchase a factory unlocked iPhone... A friend of mine recently purchase his from JAB Cellular and he loves it, and loved the service he received from JAB Cellular.com.. The phone was Hong Kong stock.. He got the 32GB size. He said it was 100% factory unlocked and he was able to update it and hook it up to iTunes without it trying to lock or anything.. I'm thinking about ordering one from them too because they still have their black Friday sale going on and the Factory Unlocked iPhones are in the sale.. I'll keep you updated on my purchase!
