Here's an interesting app for your Windows Phone. Meeting Rooms is a utility that allows you to check the status of your company's meeting rooms and reserve them from your Windows Phone.
Setting up the app is a little on the hit/miss side but it appears that you'll need to configure the app to your company's server. Then you add the meeting rooms that are available for scheduling. From there it is a simple process of finding the date and time of your meeting and seeing what rooms are available.
It's a shame this app isn't compatible with the dry-erase board that I use to reserve conference rooms. But, if you have a meeting reservation system on your company's server, Meeting Rooms might give you an advantage in locking down that conference room.
Meeting Rooms is a free application that you can find here (opens Zune) over at the Marketplace.
