uhm i think u guys are right about the fact that the k550 doesnt support flash lite (the entire K-series doesnt, i think) BUT the w800 does...

a CID36 W800 running R1L002 can be made to use flash menus as it supports flash lite 1.0 but for some reason sony removed this feature in newer firmware...
