The service Google snatched up in 2007 that lets users attach multiple phones to a single phone number is officially closing its doors on December 31st this year. An email went out to users of the service stating Google's intentions to close the doors on GrandCentral.com.
No big deal though, because Google Voice is GrandCentral's replacement -- and it's better. If you are currently using GrandCentral, Google recommends you "download any messages or contacts that you want to keep".
Dear GrandCentral User (UserName): We're writing to let you know that we will be closing down the GrandCentral website as of December 31, 2009.
All GrandCentral accounts were upgraded to Google Voice earlier this year, but since that time, you've still been able to log-in to your GrandCentral account and listen to old messages there. You will no longer be able to log-in to your GrandCentral account after December 31. Because of this, we strongly suggest downloading any messages or contacts that you want to keep in the next 43 days.
We will send you another reminder before closing down the site, but we suggest you take action now to download any information you want to keep.
