Ok, I'll stop gushing about the iPhone. But one thing I noticed on the developer guide was that the iPhone doesn't use RTSP/RTP for video streaming, but rather HTTP byte-ranges.
This is yet another big reason for servers to support full HTTP 1.1. Hopefully pipelining won't be far behind :-)
Another interesting note is that, as expected, Web / Phone / Email / GMaps integration is purely conducted via hyperlinks, i.e. the tel:, mailto:, or http: schemes. URIs with a "maps.google.com" authority are redirected to Apple's implementation of GMaps. Numbers in text that look like telephone numbers without an explicit anchor are automatically inferred as hyperlinks.
