So there is a relatively new service called Grand Central that allows you to have one unified phone number that will forward your phone calls to any phone you’ve got (home, office, cell, Blackberry, whatever).
When you sign up (for free), you get a new custom phone number that belongs only to you. Then you can customize all sorts of different calls from different people to different places and do all sorts of other cool things. I’m here: (773) 321-8146.
