iPhone accessibility – swipe to scroll

Having played with accessibility on the iPhone it is clear that iOS must be the most accessible device yet.
However I think I have discovered a weakness in the scrolling system and a solution for the flaw.

The following feedback was therefore recently given via the iPhone feedback form – let’s hope it gets seen

Three finger scrolling for the visually impaired could be dramatically improved by enabling the action that brings down the notification panel (unused during VoiceOver) to be used from each edge of the screen to scroll.
it is very easy for a blind user to feel each edge of the device and swipe across the screen rather than swiping with three fingers, which sometimes drag and don’t always perform the desired action.

For those who don’t need accessibility the same gestures from the left, right and bottom (but not the top due to notifications) could be used to move the cursor in a body of text as though using arrow keys.
Perhaps a swipe would move one character in the swipe direction. Swiping but then pausing mid swipe might cause the cursor to continue moving one character at a time until the finger was removed from the screen.
