Vintersturm has updates his port of ScummVM to the iPhone.

Changes:

* Both “sides” of landscape mode now works (meaning you can hold your phone/iPod both ways)
* Misc optimizations
* Sliding a finger (very quickly) across the screen (holding no other down), now triggers arrow key events (temporary input method for this).
