[Mod][3-9-2011] Stay Awake Option in Dev Settings
Hey folks,

Saw enough people wanted this to happen, so I made it so. One of my few successful mod attempts

This puts back the Stay Awake option from Eclair, that Samsung was so nice to remove for us. This assumes you have the 5 lockscreen mod from sbrissen already installed. I have only tested on superclean.

Use at your own peril.

If you like what I do buy me a brew. <~~~~DONATE to adrynalyne
