After the update, I played Aurora Feint (in the interest of science 😉), updated my calendar and contacts, added another app (I have over 40), and updated my YouNote app. Then I did a sync, to see what would happen.
It only took about 5 minutes.
In the interest of full disclosure, With 2.0 and 2.0.1, my syncs have taken anywhere from 10 minutes to over 2.5 hours, with no rhyme or reason. I sync very often, at least once a day, and I would go from a short backup to a long one or vice versa with no change to my iPhone.
