you need a build.prop edit
i've tested this on the new OTA 33R and 38R stock.
works like a charm.
i hope people will build this into their customs, if they haven't already
go to /system
edit /system/build.prop. you'll need an editor with root access and r/w privileges
add to the end of the file
now someone make a simple script app for me so that i don't have to write this every time i flash, lol.
