Will Apple unlock iPhones?

[imutter]

So here is what I am thinking.
I always got contract phones afterall I am satisfied with AT&T and we were never going to switch and got gradfathered in with our plans.
This time around I have to look at this a bid different. We may move overseas next year (there is a good chance) so I will need unlocked phones. The iPhone 5 I buy without contract and hope it is available unlocked. Here is
Question 1
Will Apple unlock it if I buy iPhone5 full price?
I had called At&T while I was in Germany and they gave me a code and tried but it did not work?
Question 2
Is Apple store the only place I can get my iPhones unlocked?
And there comes
Question 3
Is Apple unlocking iPhone4 / iPhone3gs after your the contracts are fullfilled?

Out can get iPhones unlocked in multiple places. Also AT&T should have unlock codes that work. I have had many phones unlocked as I go to Italy frequently. Do it before you move

Also make sure where your moving to uses the sane frequencies if not it will be for nothing
