Hey.. I've been looking for a way to solve this problem for a while but now it's urgent and this forum looks useful :( I put the SIMLock code on my D600 (this is the code that stop you putting in a different sim card without entering the code) and now I've forgotten it. I rang the help line and it's gonna cost me £22.31 to completely reset it. Is there a way that I can do it at home quickly and for free or at a cheaper price? Thanks very much.
