Or is it really 1.5 million WP7 users? I don’t know, and I wish I cared more. I’ve never been a numbers guy, and personally, I was more excited to see that the WP7 Facebook app has recently been shown some necessary love. (Sorry Steven.)

The two largest updates being featured is the ability to tag photos, and integration of Facebook’s latest big product release, Places. After using my friends WP7, the update also seems to fix some issues where the application seemed to struggle with basic actions such as loading profiles. There also seemed to be some small aesthetic improvements and light touches to the design of the app that aren’t necessarily a big deal, but nice to see anyways.

Sadly, the Facebook app for WP7 does not take advantage of live tiles or notifications, as pointed out by WP7central. Why the application has yet to do this, I have no idea. Live tiles are a very unique property of the WP7 OS, not taking advantage of this is sort of depressing, but I am sure that will change soon

All in all, it’s a solid update to a rather lackluster Facebook application in comparison to the iPhone and Android. Still, props to Microsoft for at least having an official Facebook application available at WP7’s release, unlike Android’s slow crawl to Facebook relevancy.

If you are a proud WP7 owner (jealousy refrained), and have not yet gotten the chance to update your Facebook application, click here for the marketplace link. After that, you should be good to go.
