I've got an iPad 2 and an iPhone 3GS, both of which have the official Facebook app. Since I set up Facebook on my iPad, only my iPad has been receiving notifications from Facebook. (I think this might also be the case with other apps.)
Ideally I'd like to receive notifications on both devices. Is this possible?
If not, how do I select which device receives notifications? Is it a simple matter of turning off notifications for a given app on one device, and leaving them on for the other?
