My iPhone 4S has the exact same home screen default arrangement as the iPhone 3GS I got on launch day. The only thing that has changed is "iPod" to "Music," but it's still in the same place as it was on my 3GS on launch day.
It sort of makes it good in that the OS has allowed me to stay this consistent, but on the flip side, it also makes it very, very, boring, as I've been using the same UI for several years now. Really craving a change! And not just a "let's just make the black keys in the Phone app white" or "let's make the volume slider keys now change color with gyroscopic movement." These are nice enhancements, but only worth of a 5.x add on. Not an iOS 6 add on.
