iPhone 4, Droid X, Samsung Galaxy X i9000, Blackberry 9700 in Japan?

[Guest fifo_thekid]

Can I buy iPhone 4, Droid X, Samsung Galaxy X i9000, Blackberry 9700 factory unlocked from outside Japan and use it in Japan?

I mean using it on their local operators since I'll be living there

Thank You

It may be possible but you would probably be better off looking at buying a device once you get over there unless you know exactly what network you are going to join and also what bands they use.
