You're going to hear a lot of conflicting information about
CDMA unlocking. Some people say it can be done (and technically it can) but most people will tell you it's a waste of time and you might as well save yourself the trouble. Most US and Canadian
CDMA providers will not activate an unlocked
CDMA phone, especially if they don't already sell the same model. Please read the following thread I authored about
CDMA unlocking, and then if you still want to pursue this endeavor, the second link I've posted is a google search with some related results. Good luck!
