There will be a system update on April 6th. that will unlock the USB flash memory feature for your Xbox 360. USB flash drives can be used to save just about anything, but lets be real its only for arcade games and demos. People are just running out of space and patience with buying a new 360 hdd. Only downside is its limited to 16gb drives. You can use two 16gb drives to make 32gb, but you cant use one 32gb drive. Yes I know, deal with it.
