In addition to patching various security holes, it looks like Apple added "Export to iPhone" and "Export to iPhone (Cellular)" presets to Quicktime 7.2 -- making it easy to spit out .m4v or .3gp files optimized for the iPhone's screen and data delivery options. This isn't a huge surprise, since Quicktime gained Apple TV and video iPod presets shortly after those products were released, but at least now compressing your videos to the postage stamp sizes required for them to stream over EDGE is just a click away.
