Do you have concrete step to know if an app is a C2DM. According to c2dm website;
"What Does the User See? When mobile device users install an applications that include C2DM, they will get a permission from Android Market informing them that the application includes C2DM. They must approve the use of this feature to install the application." This is the permission in the Manifest file of the C2DM app; <permission android:name="com.example.jumpnote.android.permission.C2D_MESSAGE" android:protectionLevel="signature" /> <uses-permission android:name="com.example.jumpnote.android.permission.C2D_MESSAGE" /> <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
