Anyhow, lex is correct. Cdma phones cannot be unlocked to work on other carriers. They are a very different animal than gsm devices, which use sim cards. Cdma phones rely on their esn, which is very device specific. Bottom line is yes, you need to buy a new phone.

As the others have said, the device will not work. Sorry about that. You might want to try Craigs List. They usually have pretty good deals, and good devices. GL, and welcome to CB.
