UPDATE 10-08-2012: Here’s a blog entry on how to determine if the device you’re on has touchevents enabled. Note that most Javascript libraries/frameworks should already have some sort of detection for this built in.
My demo for using Cubiq.org’s SpinningWheel control stopped working on iOS6. The issue was that I only implemented a mouseup event to show the SpinningWheel. Once I added the touchend event in addition to the mouseup event, all was working. I can only assume that Apple removed mouse events in iOS6.
