-After installing 2.0.1, each successive backup is much faster.
-Apple may have changed the calibration of the iPhone's reception "bars" while connected to a 3G network to reflect a stronger signal than before.
-Keypad loads quicker.
-Screen rotation in Safari appears to be smoother.
-Some apps may ask to be updated after the firmware upgrade.
