I want/need this patch so badly. The concept, when the screen is on, data turns on, when the screen is off, data turns off. Im willing to donate, yes you saw it in the title, 20 DOLLARS, for any patch devs out there that can do this. I find myself using my phone only occasionally and this patch would be a tremendous benefit instead of having to toggle data on and off each time. I may be crazy, but there's some other people out there with my same train of thought.
