ios - "fb://" url scheme - official or not?

Question

Some dev blogs have published information about the "fb://" url scheme for opening various views in the Facebook iPhone App. No matter how much I've searched, I haven't found one word from any official Facebook source about this.

Since the information is public anyways, I'm sure I'm not the only one who'd like to know, whether using this url scheme is officially approved, am I allowed to use it, does it work correctly, and if it's not approved, will it be and what's the approximate schedule for that?

Thanks in advance for any info on this subject!

It's there to support the iOS push notification system (i.e. you get a push notification that says "Friend's Name tagged you in a photo", and you tap on it, it takes you straight to the photo).

I'd assume it's not intended for third party use and therefore subject to change. Hell, Facebook's public-facing APIs are subject to change on a whim anyhow, so I'd be especially cautious about something they hadn't documented.
