I upgraded my 4S today and it was very laggy at first, until I noticed that it had decided to background-launch every app on my phone. I quit all of those from the app switcher and it's back up to its usual speed
Interestingly, a coworker upgraded his and it didn't launch all of his apps. I'm not sure what triggered that on mine.
