Hello guys, I have been reading this forum and had gained courage to try and unlock my Nokia 1600, however after using codes generated by http://www.gsmevolution.com/freecalc/ http://www.lur.nu/unlock/nokia_eng.php http://unlock.nokiafree.org/dct4.php Which all generated the same 7 codes... I tried enetering the +1 version then the +7 version and finally the +5 version after every single one it said "Code Error". Can someone please help me unlock it because I only have 2 more tries. I am assuming that the firmware of this phone may be newer therefore the codes dont work. Here are my details Make/model phone: Nokia 1600 (Firmware 5.53) IMEI #:352739017221737 Country the phone is locked in: Australia Provider the phone is locked to: Vodafone Thank you for your help.
