I'm back what did I miss

I have been away in android for the past 3 months. I went from my iPhone 4 to a galaxy s2 skyrocket, to a galaxy s3, and ordered a nexus which is on back order. So I am on my iPhone 4 until my nexus ships. Anything cool happen in the world of iOS. Also I am on iOS 5. Is iOS 6 worth it. I think I might stay on iOS 6 purely because of google maps.
