I've read that Quicktime movies in web pages actually work in Safari when browsing the Internet with the iPhone, but how do they display?

Do they display in the website just as they do on Apple.com within normal browser-window, or are you taken to a new page with the video only?

They display in the browser, the Quicktime app actually runs inside the browser.

It's pretty cool, you could encode a bunch of iPhone-friendly versions of your DVDs, host them on a webserver and then have a whole repository of movies for your iphone at your fingertips.

Your "unlimited" data plan will have fair use limitations. I'd guess downloading and watching movie length files repeaatedly would blow through the fair use limits pretty quick resulting in AT&T cancelling your contract.

Simply bandwidth and hence video quality reasons I think that using WLAN would be better than EDGE so the carrier becomes a non-issue.
