Vinterstum has released a new version of ScummVM for the Apple iPhone, heres the latest release news:
New update: 20071124_2250
* A mouse-moved event is now always sent before a click-event is sent, which should fix the problems with clicking on things in Broken Sword
* Added a workaround which should take care of the issue where the cursor would get "stuck" as if you were always holding one finger down.
