I'm getting errors when trying to install just a few things... and one of these is pretty petty, but just so you know what's going on...
attempting to install Air control game...

EDIT: Unmounting the SD card allowed both to install.
EDIT2: Used Root Explorer to find smdl2tmp1 and rename it smdl2tmp12 temporarily. It then sort of allowed me to install the apk. It hung up during the installation, as in never said the install completed, but when I backed out of that, it was in fact installed and working.
