i have the same problem. did rSBT solve it? i installed the nullriver installer app, and the field test icon just appeared..... my screen went black today and i want to get rid of it. also thinking about eliminating the installer app, but can't figure out how.....
Mine is the opposite. The program is still on my iphone, but not the icon. I want to get rid of the app, but it doesnt show up in installer to uninstall.... help please..
