I just saw this video on the brilliant German Apple site fscklog.
It shows a new way to navigate text in iOS5, but it seems to be only available in Apple’s iWork applications as of now.
When trying to navigate inside a word for example, instead of invoking the magnifying glass — which can be unreliable sometimes — the user can now make short swipes to the left or right with one finger to move the cursor one character at a time.
I sincerely hope this is part of an official API, because I know a few apps that could make great use of this.
