The App "Fahr-Info Berlin" was not banned from the iTunes App Store.
There is a mistake in your article:
The App "Fahr-Info Berlin" was not banned from the iTunes App Store.
The BVG just wants, that the graphical overview of the subway lines - called "Netzspinne" in German - is not part oh Jonas Witt's iPhone-App anymore.
But of course, the BVG should be more thankfull to Jonas Witt and award him with a lifetime free ride on their busses, underground- and speed-trains and trams!
