=> firstly, are we %101 certain that the 6YS1 firware on this page here:-
**IS** the genuine/original/unchanged SONY 220 firmware ?
=> secondly, [assuming it is] can you flash it into an E1 drive or is it only for A1 drives ?
=> lastly, [ again assuming it is genuine] has anyone flashed thier 210E1 to the 220E1 using this 6YS1 firware ? If so - any problems / glitchs / issues ?
