Wats the whole module thing do, is it really that good? and if o, can someone list some here and wat they do.

iv updated to 2.71 SE-C from 2.71 SE-B1, i though that itwould let me load iso's without umd, even though i skiped 2 firmware's in between? if i want to have all features do i have to downgrade to 1.50 and go through all the steps?
