K550i CID53 unlock help needed

[fuertesue]

After doing Sony updates for my K550i my CID changed,  I had bought an unlock patch for CID51 before updating software, had run it through XS++ and it showed CID51 ran it again after updates and then it showed CID53, now the patch won't work with CID53 so I wasted my money.
Will have to get a new patch or unlock code but which is the best and cheapest as I already paid for one, as  far as I know there is no free patch available as yet and ideas !!!
Many thanks
