Android's Facebook app got an update yesterday, bringing it to Version 1.2 and bringing native inbox support along with it. In exchange, you lose the option to take and upload a picture from within the main page you see above, but that's not really a big deal given how easy it is to do from the native Android or Sense (or Motoblur or whatever) camera apps, and you can do it from the news page. We'd still like to see Facebook chat, and maybe less reliance on the mobile site, but it's still a welcome update.
If you haven't updated yet, take a gander in the Android Market downloads section. Thanks to everyone who sent this in.
