Tap on a restaurant and you'll get hours, phone number, website (if available), address (with a map), and star rating. Tap on the rating to read a few selected comments, to check in at the location, or to write your own tip. (The latter two launch the Yelp app if it's installed on your system). You can also tap on the picture in the top left corner to view photos, which also gives you an option to add your own (again, via the Yelp app).

Best of all, if the restaurant uses the , you can tap a button to make reservations or even have Siri do it. "Make me a reservation for two at 7pm on Wednesday night at Ruth's Chris" pops up a panel telling you whether or not tables are available at your chosen time. It even offers you the option to shift that time in one direction or another. Tap Make Reservation, and the OpenTable app will launch (if it's installed on your phone); if not, you'll be prompted to download it. Of all Siri's features, this is the one that strikes me as the most futuristic: I just told my robot assistant to make me dinner reservations and it did.

Beyond those new features, there are a good number of other tasks that Siri can accomplish in iOS 6. For example, you can now launch an app simply by asking Siri to do so. Want to post a tweet or update your status on Facebook? Siri can handle that as well, if you've set up your social networking accounts in Settings.

In general, Siri handles certain things a little better now than it did previously. For example, it's now possible to change the text for a reminder while you're creating it, and it's a little more streamlined to send someone a message via Siri.

However, Siri . The virtual assistant still can't read your email to you, or change your settings (though it will recognize commands to turn on Airplane Mode or Bluetooth), and trying to edit an email message or iMessage you've composed via Siri is liable to induce hair-tearing for anything but the shortest messages. And much as I would like to be able to offer an opinion on Siri's Eyes Free mode, it's surprisingly difficult to get a BMW test unit.
