Compile JellyBean's Keyboard for ICS Rom
I literally had to scavenge the code up and down to get to the solution. A xml called defaults.xml contains the default input method node. That needed to be changed to the package name of the JellyBean's LatinIME. This is yet to be tested; will let you all know if it runs okay.



Edit:
This worked. Please go ahead and get cracking.
