Availability of update depends on Product Code / Region..also if the phone is Network locked, then the update is possible only after an approval from the Operator.. It seems Nokia is yet to make any updates available for your phone.. so wait and keep checking...
One more way to confirm is..
As I have mentioned, the Nokia site shows the latest version available.. but that MAY NOT be for YOUR phone..
As a final go, you may try getting the latest update thru' Nokia Care.. as there are reports that in few cases that was possible..

Doesnt matter if your phone is unlocked, it still carries the product code recognized as an operator model if it was acquired via an operator, and still needs operator approval before it updates.
MODERATOR'S NOTE: This post has been edited because you mentioned about an unauthorised procedure that may invalidate the phone's warranty; hence we do not allow it to be discussed on an official Nokia forum.
