I just successfully upgraded my 8900 wirelessly to 18.104.22.168. There has not been any announcement as far as I know so I was surprised when I clicked upgrade and it actually worked.
Has anyone else had success with this? After trying to duplicate the upgrade with some friends, they had to click wireless update and it would say none available. Go back out and try again. After 4 or 5 times it found the update. Strange. It took about an hour to back up the device and another hour to load the OS. I believe the update was only 9MB when it downloaded.
