Apple Store is back up, gives more detail on the digital adapter

The Apple Store is back online and features information for the iPad 2, along with the iPad Smart Cover and the Apple Digital AV adapter, which also supports video output from the original iPad, iPhone 4 and current-generation iPhone 4, but mirroring will only be on the iPad 2. Video out supports up to 1080p for the iPad 2 and 720p for the original iPad, iPhone 4 and iPod touch.

The iPad 2 will be available starting March 11, and there are no pre-orders.
