sorry for my late reply, because i went to a project construction site and there is no computer there... whew. :)

anyway, about your question:
IT IS MORE OKAY IF YOU GET 1.1.1 VERSION:
to check if its 1.1.1 iphone, look at the back of the box and look at the serial number.
1. if "4th and 5th" number in your serial number on iphone is 44 and below, IT CAN BE UNLOCKED. (this is 1.1.1.)
EXAMPLE serial number: 7V744Y9LWH8 - see, this is week 44 on 4th and 5th digit number. all week 44 and below can be unlocked.

BUT IF YOU GOT VERSION 1.1.2:
2. if "4th and 5th" number in your serial number on iphone is 45 and above, it CANNOT be unlocked.
EXAMPLE serial number: 7V745Y9LWH8 - see, this is week 45 on 4th and 5th digit number.
now you need to get TURBOSIM to unlock it which you can buy also in states or via FEDEX.(but beware fake or scams..ok?)

i hope this infomations help. :)
