Since there is no minimalist ROM out there I'd figure I'd give it a shot.
This ROM is a bare bones 3.70 ROM based off of SteelH's ROM SteelROM RevI. It is stripped down to almost nothing while still being fully functional. Sense has been pretty much stripped to it's minimum. Almost all apps, wallpapers,and widgets were removed. The rest of the apk's were zipaligned. No boot animation, or sound. It seems that everything works but I make no guarantees. Use at your own risk. This ROM works best if you flash Calkulin's All in One Radio update after flashing this (if you haven't done it already). This is pretty much a build it yourself ROM that is fully functional without all the bloat. Just add app's, widgets, and a theme.
Remember always NAND, and fully wipe before flashing.
