Hello, I am trying to unlock my Nokia 6170 but I have not yet succeeded. I tried downloading the NokiaFREE Unlock Codes Calculator v3.10, but the Nokia 6170 appears 2 times in the pull-down menu, so I tried using both but it did not work. Can you help me? My IMEI is 355658000627618, and my carrier is TELCEL in MEXICO. My phone model is Nokia 6170b. Thanks!
