Walt Mossberg, in his blog on allthingsd.com answered a bunch of questions regarding the iPhone. One of the big answers was that the iPhone will soon support Flash which it's Safari web browser is currently lacking.
From the blog:
Q: If the iPhone’s Web browser is so good, why can’t it play video on Web sites I visit?
A: At launch, the iPhone version of the Safari browser is missing some plug-ins needed for playing common types of Web videos. The most important of these is the plug-in for Adobe’s Flash technology. Apple says it plans to add that plug-in through an early software update, which I am guessing will occur within the next couple of months. However, a separate program included on the iPhone can play a limited selection of videos from YouTube, and the phone can play videos you purchase from Apple’s iTunes store, and certain videos you create yourself.
