The meat of claim 1 is: "instructions for detecting one or more finger contacts with the touch screen display;
instructions for applying one or more heuristics to the one or more finger contacts to determine a command for the device; and
instructions for processing the command;
wherein the one or more heuristics comprise:
a vertical screen scrolling heuristic for determining that the one or more finger contacts correspond to a one-dimensional vertical screen scrolling command rather than a two-dimensional screen translation command based on an angle of initial movement of a finger contact with respect to the touch screen display;
a two-dimensional screen translation heuristic for determining that the one or more finger contacts correspond to the two-dimensional screen translation command rather than the one-dimensional vertical screen scrolling command based on the angle of initial movement of the finger contact with respect to the touch screen display; and
a next item heuristic for determining that the one or more finger contacts correspond to a command to transition from displaying a respective item in a set of items to displaying a next item in the set of items."
(Notice the ands.) So this is claiming the ability to distinguish three different specific gestures.
(Besides Graffiti, I don't remember old touch devices using gestures at all, although I'm sure there were some.)
