Facebook released an update to their SDK.
coincidentally I only downloaded the SDK yesterday for a new project that I started on the weekend. Some great pre built code such as a native code friends picker thats going to be super helpful to many developers.
From the Facebook dev site
We're happy to announce a major update to the Facebook SDK for iOS that makes it easier and faster to develop Facebook-integrated iOS apps. We've also introduced a new iOS Dev Center so you can quickly access the tools and resources you need to build great social apps for iOS.
