In case any one is curious I got this email from amazon about 30 min ago:

Hello from Amazon.com.

Thanks for ordering the Nokia N900 Unlocked Cell Phone/Mobile Computer. When you placed your pre-order, the detail page incorrectly indicated that the phone will work with AT&T 3G within the United States.

The Nokia N900 only works with T-Mobile 3G within the United States. If this wasn't what you expected, we understand if you'd like to update or cancel your order. You can make order changes here:

Maybe now they are clearing up any loose ends and getting ready to ship...
