    Default CDMA Basic Terms

    CDMA VOCAB Basic terms

    This will help you understand some of the basic terms used in phone flashing.


    Flashing vs. Unlocking: The technical meaning of flashing is rewriting the Firmware (software) to a phone. Although it is more commonly used when referring to changing a phone's settings so that it works on a different provider's network e.i. Verizon to Cricket, Sprint to Metro PCS... ect.
    Unlocking means entering a specific code into a GSM phone so as it will accept a different providers SIM card to be used on that network. We will not be discussing this in this section.

    TDMA: Time Division Multiple Access/Digital AMPS- This 2G technology and has been basically phased out.
