Here’s yet another reason to pick up an iPhone/iPhone 3G if you don’t already have one – Facebook 2.0 is now available via the iPhone App Store. This new version will include overviews of what’s going on in Facebook, including News Feed, Live Feed, Events, Notifications and others. Not only that, you’re able to see those new tabs in Facebook’s revamped design, in addition to the ability to both post and tag photos from your iPhone. One of the more interesting aspects is refreshing the page simply by shaking the iPhone – a novelty that’ll wear off in due time, but convenient to say the least. Folks who aren’t iPhone users but use the mobile Facebook version will miss out on this though.
