Sometime soon, Facebook 3.03 for the iPhone will be available in the App Store. It should be a small update with some bug fixes. The bigger news is what will be coming soon after it: Facebook 3.1 for the iPhone, complete with Push Notifications. While we've long suspected that this would be a feature in the next major iteration, developer Joe Hewitt confirmed it tonight on Twitter. And that feature will make what is already one of the best iPhone apps out there, even better. The lack of Push Notifications is probably the biggest complaint users have about the app, right now.
