I don't think any device that currently has a 4.2 build for it even have SD card slots, so it makes sense that option isn't included. I would recommend if you're running cm10/aokp that after you paste this into /system/app/ that you reboot into recovery, wipe the dalvik and fix permissions. The first time I tried this I had some rather weird glitches in the gallery, and a force close of the camera. After doing it over again with the dalvik wipe and fixed permissions, everything works fine. Haven't tried the sphere camera yet though.
