Story Behind BBSAK
BBSAK was built as a JL Cmdr replacement tool with a more friendly GUI, developed by two hobbyist developers. It has grown to what it is today, a windows application with many funtions for modifiying BlackBerries. It uses Javaloader to do its magic. We hope that you all will find it as useful as I do.
