I have calculated the unlock codes with CybergsmDCT4Calculator14 and got the following codes:

#PW+399566425727165+1#
#PW+397146626523442+2#
#PW+037223162534525+3#
#PW+735440367346747+4#
#PW+477947103501541+5#
#PW+335076366332575+6#
#PW+378466106656562+7#

I have tried code 1 with inserted SIM card, and the phone said "Restriction removed". After that i have tried code 7 without sim card, and the phone says "Can't change restriction"!

Is the phone now unlocked or not? I have no other sim card to test it!
