A new version of the iPhone OS is floating around. 2.2 beta 2 doesn’t include cut and paste, MMS, or the ability to heal the halt and deaf. It does, however, have Google Street Views. You’d best tell grandma she can stop wetting herself in anticipation. There is still no cut and paste.
As for Snow Leopard you’ve got a new Finder written in Cocoa (tell your Uncle he can stop working on his version), Exchange integration (tell your Pa he can stop working on his version), and the cousins will be disappointed to find out that it has an ImageBoot function that may or may not boot images.
