to unlock the iphone 4 and according to the database it is unlocked. But are they real or fake? Since the instruction say that I need to update to the newest firmware to unlock the phone and once i do that there is no coming back.

You need to first jailbreak your 5.1.1 and save the blobs. That way, is you're forced to update to iOS 6 you can revert to 5.1.1

(I'm hoping I'm interpreting your post correctly?)

iphoneox correctly confirmed that my unlock was real

It is too late to save 5.1.1 hashes.
It is not necessary to be jailbroken to save hashes (TinyUmbrella), but still too late to save 5.1.1 hashes
