Most you guys fail.
Google xbox 360 and firmware upgrade and flashing vs software upgrade. Than you understand why the 30 beats the PS3 hands down.
Firmware is the stuffs "on" your 360 DVD Drive to actually make it "work". There are no "upgrades" for it, only custom firmware to enable it to play backups. Is this what you are on about? If it is, well this has existed since 2006.
Are you maybe talking about Jtag?
Just make your first post clearer, as it really doesn't make any sense.
