hey ppl
u want flash for playing flash games or for viewing web content .. (mostly videos)
if its the latter then there is a browser called skyfire that has its own flash ( just like mozilla has a build in falsh plugin)
works well on fit and u can watch all video sites
also it streams videos very fast by compressing them to fit mobile screen saving bandwidth

skyfire browser
if its the former then U CANNOT PLAY FLASH CONTENT GAMES OR ANYTHING ON SAMSUNG GALAXY FIT BE IT GINGERBREAD OR FROYO
