Wow, congratulations! Do try out CoverScreen OS, you would be probably the first one ever to try it on a physical device (I have been testing on a remote device, and it has been quite painful and slow.)
I pre-ordered on the announcement day and had a ship-date of August 26th. But Federal Express now says the package will arrive on the 23rd. I don't think they bill my credit card until they ship, so it's in their interest to send the Flip4 as soon as practical, I guess.
