This question is a refreshing change of direction from the standard, “I shot my movie on my cell phone, how can I make it look like I shot it with a Viper?”
I think that there are three elements that make cell phone video look like cell phone video: the user, the camera, and the compression.
For the user element, you should might strive to flatten your lighting a bit and add a touch of camera shake where appropriate. For the bad camera, hopefully you’ve shot with deep depth of field, and you might add a slight fisheye. For the compression, you could blur and mosaic the chroma to simulate low chroma subsampling; add some sharpening until the image looks decent, then add a bit more; and add some subtle or not-so-subtle macroblocking (mosaic) periodically on areas of high motion.
