iUI is a JavaScript framework to make coding pages for the iPhone really easy. Joe Hewitt’s (of FireFox, FireBug, and FaceBook fame) small JavaScript library can transform simple lists and links into an experience much like a regular iPhone application.

iUI uses many CSS3 properties with images ripped from the iPhone itself to create the distinctive interface, complete with sliding animations and Ajax page replacement. He points out in a Y!UI Theater video that Safari Mobile lacks many events found on regular browsers due to lack of ways to input those events on a touch screen, as well as having no mechanism to access flicks used to scroll in native applications.

Despite the limitations, knowing such an easy to use solution makes me want to download TestiPhone and write something for iPhone, even though I don’t own an iPhone. I would take Eric Meyer’s concerns into account, however.
