Interesting...my knee jerk response would be that he has a firmware problem...ie did not install correctly which has secondary effects on things like applications.
As far as installing firmware is concerned, I have found that people who downloaded the update (without installing), and unsync'd personal data off the phone before installing have had zero problems with 2.0 or 2.0.1. The problems seem to arise with the fact that iTunes seems to be "buggy" in general (timing out processes, not removing certain apps, etc..). The thought process behind this is mitigating the risk associated with iTunes processes by giving it less to do (ie very short backups as part of the firmware update).
The other point about an "extra dot" indicating an extra page with nothing on it.....he wasn't very clear on if that extra page was still showing after he pushed the home button. Extra page will always appear when moving icons around.
