system update enabling USB storage is live and ready to help you explore the joyous world of non-proprietary storage options. Rules are the same as previously noted: USB devices need to be over 1GB, but can only use 16GB of available storage. Users can use two sticks at once for 32GB, but can switch out units any time, limiting their storage potential by how many USB devices they've got lying around.
The update takes approximately five minutes with a standard cable connection. For those who don't believe in internets, the update will also be available on the branded 16 GB Xbox 360 USB sticks set to debut in May.
