"If Nanully says "If you take the SD card out of a Blackberry Storm and it doest not work, it is an infringing product", what is the cause of infingment?"

What that means, it is not functioning with the Microcontroller and most notably the caching memory. The cach is a tiny highspeed RAM(SRAM)as opposed to a normally utilized RAM resource for shadowing files. If you pull the module while a file is executing the device stops playing.....where if a file was shadowed to a normal RAM resource consideration it would continue to play when the module is removed.
