It is possible to update your BB to any OS level that has been released by any carrier for your specific model BB. You can use this procedure:
If you choose to use an OS package that is not from your home carrier, then insert, between steps 1 and 2, the deletion, on your PC, of a file named VENDOR.XML.
You will have to research what versions different carriers have released for your model BB.
