which version do I get if I buy iphone 4s at the apple store ?
16GB, and you can choose black or white.
which vrsion do i get if i buy iphone 4s at apple store, 6.0.1 or 5.1.1 ?
Likely iOS 6. That's not a problem.
And if I want to buy the iphone with version 5.1.1 ?
You cannot pick what version of software you want. I can't think of a single reason why one would not accept a phone unless it is running an old version of software.
