im getting some overall lag all throughout my iPhone as well..nothing that's halting me from using my phone as usual but annoying all the same
probably just a firmware issue that will get patched in a later update?
Most everyone is having this problem. It was supposed to be addressed (or so we thought) in the 2.0.1 update, but has come back with a vengeance. No need to worry, it will probably be cleared up for sure in the next update.
