Sprint PPC6700 Used Overseas With RUIM Card Slot

[brabus]

Hi there, I have a PPC6700. I am using this device not in the US but overseas. My unit happened to have a RUIM (Name for SIM in CDMA) Slot. I am very curious to know wheteher any of you guys have succeded in finding a Radio ROM that will make this RUIM Slot reads Phonebook from the RUIM Card. Because back home we use RUIM card for flexibility. You don't need to go to Service Provider if you want to change the PDA Phone you have. Any suggestions and comments are welcome.
