OK, I need some help. I have a co-worker/friend that is working in Japan for the next 12 months. He asked me to find a "factory" unlocked 16G iPhone for him so he can use it in Japan. $400 is his limit.
I did a quick check on the Apple website and they are $550. Other than Ebay, Craigslist, or some shady looking dude on the street corner, where do I get one?
