The main points of iPhone 3.0 I've taken away from the headlines are:
-cut/copy/paste
-MMS
-spotlight (universal search)
-ad hoc peer-to-peer network
-bluetooth A2DP
-synchronization support for CalDAV and .ics
-new APIs: push notification, in-app e-mail, proximity sensor, shake detectors, etc.
-free upgrade for iPhone, $10 iPod touch upgrade
We first reported on it in the weekend news, in which there was thunderous applause for copy and paste in the video clip from Diggnation.

Video recording and multitasking are two obvious omissions. I've updated the "iPhone vs. Pre" compilation with a couple new articles.
