I think unlocking Tracfones will do you no good. You will not be able to use another carrier's SIM card in the phone. The best way is to get it reflashed/unlocked (Re-programed) so that you can use the T-Mobile or Cingular SIM cards in them. Once you get them reflashed, you will NOT be able to use the Tracfone SIM card in it. Fix it here: http://unlocknokia.byyourcommand.net/viewtopic.php?t=4373 JG
