Where's Facebook 3.0??

I've heard that it's out, but it's not showing up in App Store. I've also seen random rumors in forums that Apple took it down due to people posting nude pics or something, but I just couldn't believe this would be a reason since you could do that anyway (not directly from the phone, but otherwise).

I did a quick Google search but didn't see anything official, just a lot of word-of-mouth. Anyone know the real story?

EDIT: upon further research it looks like it just hasn't been released yet. No push yet either, which is odd. If they're still working on it, why not work a little longer and include push?

I was wondering the same thing. I saw a review for it online, so I rushed to update, and nothing was available. That was over a week ago...
