I would like to downgrade my adobe flash lite 3.1 in my 5230 (long story, don't ask), but how is this going to change my phone? I like to watch a lot of movies and tv-shows on my phone, and does downgrading limit it? I usually watch movies etc. from the memory card in mp4, does it use flash lite or realplayer to view the video? And is there anything else, which downgrading might change?
