How do I enable push notifications for Facebook for Android? I'm currently running the latest stable release of CM7 for the HTC Droid Incredible and Facebook for Android 1.6.4 (released on 20 August). According to Facebook, push notifications are enabled for devices that support them. Since I get push notifications from other applications (such as Google+), I know my device supports them.

I've read about various problems with them, but I haven't found any definitive solutions (or a definitive lack of a solution). I would assume the setting for push notifications would be in the application's Settings menu. I have a number of options for various times to pull notifications down, but I don't see an option for push notifications in the app or on the Facebook website.

Is this just a broken application or am I missing something?
Funnily enough, as I just noted here I believe that the app is just buggy and unreliable.  There's no reason for the individual device to determine whether the application can do something like push notifications.  Android's cloud to device messaging requires 2.2 or higher, and the Facebook post notes that that's what they require as well, so I assume that's what they're using. C2DM works perfectly fine for other apps so the only reasonable explanation is that the Facebook app doesn't work properly.

The app was updated recently and does work better for many users, though, so make sure you have the latest version.

There are no settings related to push messages in the app or in the Accounts and Sync settings.  Regular sync is every 3 hours at most, which seems infrequent to me &mdash; my BlackBerry allows updates every half hour.
