This morning Facebook announced improvements to their iPhone and Android apps, as well as changes to how they handle their sign-on platform. First, the new Groups and Places features are now fully integrated into both apps, which also brings up the Android app to be on par with the iPhone one. This will allow you to take part of all those groups while on the go. Their mobile apps hadn't been updated in a while, so it's good to see the company commit themselves to the mobile space. As a side note, they did comment that Facebook had no plan to make a phone of their own, preferring to instead bring their platform to the devices that people use.

The second part of the announcement dealt with single sign-on. Mark Zuckerberg described the troubles and frustrations that entering usernames and passwords could be on a phone, and their approach to solving it. They are now providing developers with a way to integrate a single button that will log users to their services. Now, to log into any mobile site or service that supports this feature, all you'll have to do is click on the button "sign in with Facebook". No more username or password to remember. They showed the Groupon and Zynga apps which will support this feature soon, with many more on board.
