I rooted my bionic, installed theory r3blurr3d rom. I made some tweaks to the gmail.apk file (in the 3xperience package). I'm trying to figure out how to set it up in its own zip update instead of flashing the whole 3xperience package, because it has some other apks I do not want to install. I dunno much about signing, and manefests and such. I've just been using apk manager to edit images and layouts and recompile.
