The ICS 4.0.4 Stock ROM was posted to StockRoms.net on the 1st of August. I downloaded and pushed it onto my tab via Odin. (unrooted) The transfer and upgrade / reboot was seamless and had no data loss. I have been very happy with the upgrade and really impressed with the additional bangs and whistles. The folder creation and ability to add shortcuts to the desktop is nice - AND I have not had ONE forced close/restart after using it almost non-stop for three days now. I also like that you can add or remove home screens (from 1 to 7 of them). VERY NICE (and official) release!
