Sunday, July 11, 2004: 1:00 pm (Area "B"): CDMA is the dominant mobile phone technology in North America and is operated by Alltel, Sprint, US Cellular, Verizon, and many other carriers. On CDMA handsets, roaming is controlled via a configuration file called the PRL. In this talk, you will learn how to unload PRLs from CDMA handsets, how to disassemble them, and how they can be hacked. This talk isn't about making free phone calls or doing anything illegal, but you will learn how to determine what you're really buying when your carrier promises "nationwide service."
