its a program, that alows you to view all the apps that are running cos say u open up comunicorder, when u have finished and closed the flip its still running, even if u open a diff app they will all continue to run and clog up the memory, making the fone run really slow, sman u can set so that every time u close the flip it flushes all the tasks so that it is completely empty, also allows things like bluejacking etc, very good program and its free, also tracker is a good program but isnt free.
with sman u can also fix the bluetooth problems.
