Ok, I must suck at searching because I've been trying to search for the answer for 10 minutes and been unable to. What are the Camera4.2, Gmail4.2 and KeyBoard4.2 mods? And if I flash the zips and end up not liking them, how do I revert to the stock Camera/Gmail/Keyboards? I'm on deodexed latest stock rom (multi-window and wifi calling).
