I don’t use iOS, nor do I intend to any time soon, but the coming availability of browser engines that compete with WebKit is going to be great for the web. I’ve heard from so many web developers that Safari on iOS is a bit of a nightmare to support, since without any competition on iOS it often stagnates and lags behind in supporting features other browsers already implemented. With WebKit on iOS facing competition, that might change.

This should be available everywhere.
