GCM notifications

Hi guys,

We're just getting started with the fabulous GCM notifications. Here are our issues:

1. The notification works well and the app receives it. But when the app is not started and a notification received - it should not appear a number 1,2,3 near the app icon? Or this happens only on IOS?

2. Do we have to set any particular permission in order to use GetSharedPreferences("...", FileCreationMode.Private);

Thank you all.
