The New York Times writes about a new service from GrandCentral in the US:
Its motto, One number for life, pretty much says it all. At GrandCentral.com, you choose a new, single, unified phone number (more on this in a moment). You hand it out to everyone you know, instructing them to delete all your old numbers from their Rolodexes.
From now on, whenever somebody dials your new uninumber, all of your phones ring simultaneously, like something out of The Lawnmower Man.
No longer will anyone have to track you down by dialing each of your numbers in turn. No longer does it matter if youre home, at work or on the road. Your new GrandCentral phone number will find you.
