I've searched around for this but no luck. What are the a/b/c partitions I see in P2ktools for my SLVR 7? I read in a menu in p2k commander that 'a' is the phone and 'c' is the sd card..but what does that mean? what is stored in each partition? 'a' and 'c' have a single folder 'mobile' with some of the same subfolders.
