Nokia Beta Labs are at it yet again - they've just dropped yet another beta bombshell, this time releasing an update version of Mobile Web Server with an enhanced Facebook application and all-new Group Calendar widget.

Group Calendar allows you to see your friends and family's device calendars in real time, so you can make appointments that suit everybody. Check out the video below for a more in-depth rundown of how it works.

The updated Facebook widget, meanwhile, allows you to automatically share your status updates. Alongside that you've got various bug fixes and performance enhancements, so it seems well worth a download - you can do so at the Mobile Web Server page.
