What have you noticed since the update? I've noticed a couple of things: - Unlocking is slightly more finicky than it used to be. You have to drag the bar slightly further down or hold out down longer. Just by fractions, but it's noticable. - Swype is slightly different. To choose another word, instead of just double-tapping the wrong one to bring up the list, you now double-tap to select it, then tap the Swype button for the list.
