I am updating right now and will check.
Just as a side note I contact my friend at Sony regarding the update and he happened to be in a meeting with the AT&T guys. The AT&T guys didn't even know the update got pushed out yet. They told him they expected it to go out later this week. Who cares as long as its out. Hopefully the smartdock gets detected by the AT&T firmware unlike the International.
I'm gonna try updating now and will have a ftf available shortly (as long as I get the update notification)

The AT&T firmware doesn't include the Backup & Restore app so you can do the simple root procedure. So you have to install the Backup & Restore app. Here is a link to it. Just extract and install both apps then you can do the root procedure: http://dl.dropbox.com/u/44704/backuprestore.zip
