@D0nMalte didnt they complain about property violations for streaming 3rd party content (5.2.3 Audio/Video downloading)? I am streaming a publicly available ShoutCast stream and they want see written permission to use this steam.

We are using the background task facility to work around another limitation of iOS, that does not exist on Android: scheduling periodic local notifications. iOS does not support abitrary intervals like "every 3 days" for local notifications. The idea was to use a background task to schedule all next days events as notifications. But if the user closes the app then our schedule task is not executed anymore, leading to certain notifications not being scheduled correctly.
