Updated Facebook Messaging

I requested an invitation to Facebook's new messaging product the day after they announced it on November,  15th, and I finally received the opportunity to upgrade this morning when I logged into Facebook.  Upon on first glance, I really like the new messaging product.  Grouping all of your communication with one person into a single conversation, giving you an @facebook email address, and allowing quick replies by simply pressing enter are all nice touches.

However, I use the Facebook iPhone app much more than I do the desktop version that is pervaded by an increasing number of ads.  Therefore, I was curious as to how/when the iPhone app would be updated.  It seems that Facebook updates it remotely the first time you open the app on your iPhone after upgrading online.  I noticed a highlighted circle, that appeared briefly,  around messages when I opened the app.  When I clicked on messages, I noticed the upgraded version that appears above.  Very slick!
