Facebook engineer and -- more importantly to us -- Facebook iPhone (and iPod touch) app developer Joe Hewitt announced on Twitter that he:
Just uploaded Facebook for iPhone 3.0 to the App Store for review. [...] I'll be posting more details and screen shots to the app's page on Facebook this week
Here's the Facebook page if you want to follow along, and we're guessing a lot of you do based on how many tweeted and sent this our way! (Thanks everyone!)
UPDATE: AppAdvice has a preview up if you want to see more.
REMINDER: No push notification in Facebook 3.0, that's road mapped for 3.1, which the developer will be starting work on next...
