The official Facebook app for iPhone has been updated with a few notable new features, including the much-needed ability to unfriend people on-the-go. Head on over to the App Store to update. Sadly, there is still no iPad version, and at this point it seems unlikely that Zuck will ever give in—though there are alternatives.

What’s New in Version 3.4

• Added Map View for Places
• Added the ability to Check in to Events that you’re attending
• Added the ability to unfriend from the phone
• Improved News Feed
• Improved notifications UI
