That policy may change as the official China rollout gets closer and the lines of real end-using buyers drop toward normal. Apple may start offering unlocked iPhone 6 and 6 Plus in the retail stores for use on secondary networks but not now. Until then, order through store.apple.com. One saving grace though, the demand for unlocked iPhones will be lower than for specific carrier iphones, so most likely the wait will be shorter.
