Here is a Google Apps package I have put together for older devices which don't have that much space on /system
This package is for Jelly Bean ROMs only!!! Don't try this on ICS!! You have been warned.
Also don't try this on ANY ARMv7 phone. It won't boot. Again, you have been warned.
-Google Now Voice. (I'm still trying to fix this...)
