I have a used Koodo CDMA Blackberry 8530 that I don't want anymore. I'd like to know if it has any market value? Can anyone else use it? Even if it can only be used in the Koodo network, could anyone buy it and activate it with Koodo? I do not want a trade-in, I don;t need a new phone. I just want to sell it cause I'm leaving the country and will close my account with Koodo.
