Anyone remember the Motorola ROKR? Yeah, exactly...
If this is the same type of move by Facebook, good on em... sometimes you learn best from failures.
What was special about it? It had a dedicated key to bring up iTunes. (http://en.wikipedia.org/wiki/Motorola_ROKR_E1)
I had the same thought: the OP's venture between Vodafone and Facebook doesn't feel like the "Facebook phone" that has been rumored for a while… but who knows, Facebook doesn't make hardware so they probably don't have the same opportunities that Apple had and they probably want the maximum availability, even if half-assed. (I would think it's harder to completely screw up an experience around posting a status than around managing and syncing a music library)
That was the phone for a while.
