Oh, is THAT why they do the glow thing? I always hated it, and wished they'd used the much more 'tactile' bounce-back behavior. It didn't occur to me that they were legally barred from using a 'method to emulate physical resistance upon over-scrolling an interface' or something.
I like the glow thing because I like to pull down on the screen, as a tic, while reading a web page. With the bounceback feature, it would actually move the page, which was annoying. With glow instead, there are no reading problems.
