Thank you always, every one! Thanks to your kind help, I have learned so many useful things so far. Like the facts that the verizon month-to-month iphone 5 is unlocked out of the box, it is well-stocked at any Apple store, and you can buy one and take it home right away if you say "device only". They are all very useful and encouraging to me because I live in Japan. Well, today, as I have been asked to buy the verizon iphone 5 by tons of my friends in Japan, and I will visit the US on Oct 2, I would really like you to answer to the following three questions. 1) How many verizon month-to-month iphone 5s can be bought at one time at an Apple store? 2? 5? 10? 2) If you can buy 3, can you buy 3 again at another apple store? 3) Do you need SSN to buy a verizon month-to-month iphone 5 as "device only"? If so, it is neary impossible for a non-US traveller like me to buy it... Thank you so very much in advance!
