Hello. I was wondering if there is an app that will allow me to mirror output from a JB iPad to another iPad. I'm running 4.2.1 and jail broken. I currently use an iPad as a video player for my kids in the car, however, I would like another monitor so there is a display behind both headrests. I was considering a 7-10 inch monitor and running a cable, however with the lower prices for the original iPad this might be a better option. Thanks you.
