with Winlock/Winopen you are able to open SIM-locks 1&4.
Unfortunately I have not found out a way to open 2&3 yet. There are some guys on the net, which say they can do it, but they want money for it.
With a phone I've got for testing some things, I had also no success in opening 2&3 the way you described. The phone always said "wrong code".
Opening 2&3 is still a problem :-(
by the way: what is the "x" in your IMEI?
