Aside from the usual informative items it aggregates, such as weather information and stock quotes, the latest version of Samsung's “Now” Hub has been updated to include support for Facebook and Twitter. Naturally, it can become quite a handy thing since Windows Phone 7 only offers native support for Facebook with its People Hub. Additionally, we find some new touches, like a new opening animation and audio effects, that pleasantly improves the overall presentation of the hub.
So if you haven't done so already, you can grab the free update though the Windows Marketplace.
