Is any application/procedure I could use to prevent certain apps from working unless on wifi? On one of my phones, I just have a 200MB data plan. I think it will suffice as long as no streaming audio/video programs or market downloads are used. Is there an app that can prevent select programs from opening unless wifi is connected at the time? If there's not a simple app that does that, any way to do that in tasker maybe? EDIT: Will droidwall do exactly this? It is a rooted phone that I need this on.
