It seems that there is an unused pinout for sim cards on the PW3. Looking further into the sim card standard it seems that they have begun to implement a purpose for the 7th (Serial I/O) and 8th (USB-ICC) pins. Rather than the standard 6 pins I have seen.
According to ISO/IEC 7816-12:2005, USB-ICC is another area in sim cards that can be utilized for additional data.
Would this be a viable place to implement extra storage capacity? Seems far-fetched, but interesting.
