Wow, I have bought iPhones unlocked as device only in the past as well, so far I have an iPhone 5 32 GB white, that I paid off via tmobile and it is fully unlocked and is prestige condition. I have my eye on the space gray 5S, not because of the fingerprint sensor, but b/c if the M7 motion sensor processor I keep reading it can do so many things with motion sensor apps to include a glorified pedometer.
