6210 second line divert symbol removal

I have successfully unlocked a 6210 but now have the second line divert symbol showing. I have tried removing it using nkprofile by enabling the second line and then cancelling diverts but so far no success. The software version of the 6210 is 5.02 which I have read can cause problems with the above method. Anyone have any ideas what to do next? p.s. I don't have a flasher cable so can't update the software version.

The second line symbol its appear only if you have a sim card with two lines try to put other sim card from diferent network and see if the symbol appear again! If the symbol appear again then go to a club nokia to update the version!
