hi, this is my firs req and i hope some one would help me instead of ignoring me.
what would i like to do is to edit com.apple.springboard.plist.
I want to add reflection dock and ability to dim screen after minute (this dime screen option was available in extended settings app)
now, i know how to add reflection manually by typing...blah some line (have it saved somewhere its ok) bit i have no clue what to change for screen dim (maybe dim is not right word... what it do is after a minute it doesn't lock your phone it just make your screen darker)

some one might wonder why i wont simple install extended prefs and do my thing but answer is when i had it installed my phone was really unstable and every time i touch in battery or signal - clock are it would froze

so anyone with a little time and knowledge is welcome to help
