The PC Suite team at Nokia Beta Labs has just unleashed a completely refreshed version of Communication Center, the PC software application that lets you manage your Nok's emails, messages and calendar entries from your computer.

The Lab boffins list the key improvements as a calendar editor, support for contact groups, the ability to view thumbnails of contacts, plus a whole raft of bug fixes and performance tweaks.

It's available to download now from Beta Labs, but you'll need Nokia PC Suite 7.0.8 or later installed on your PC, and it won't work with Macs - just computers running Windows XP and Vista.
