They will find you... if you want them to.

Most people have a home phone, work phone and at least one cell phone. Wouldn't it be nice to give your family, friends and co-workers one number to get in touch with you. Now you can and it's a great free (at least while they are still in beta) service called GrandCentral.  

GrandCentral provides you with a local number that you can give everyone to contact you. It allows you to tie all of your phones to that one number so when a person calls your GrandCentral number you can have one or all of your phones ring depending on how you configure your setup. The setup allows you to add your contacts and classify them into different groups. You can then specify which phones ring when a person calls from a particular group. For example, you add your mom to your contacts and classify her into the Family group. In your settings you setup your Family group to ring your cell and home phone (not your work phone). So the next time mom calls your new GrandCentral number both your cell phone and your home phone will ring and the call will be routed to the phone that answers first.

In addition, there are many other nice features that GrandCentral offers like call screening, voicemail notification and call switch.

• Call screening will either read the name from your address book if the caller already in there or GrandCentral can ask for the callers name if he or she is a first time caller.
• Voicemail notifications can be sent to you via email, SMS or both. A link is provided in your email to listen to the message.
• Call switch allows you to switch between phones while you are on a call. For example, if you are talking on your work phone and would like to leave the office, you can press the star key (*) and your other phones will ring. Simple answer on your cell phone and hang up your work phone.

GrandCentral is a great service that can really help bring back some simplicity to our complicated (ala multi-phones) lives. Moreover, I believe that it is going to be a service that will continue to grow and mature. I believe that this is especially true since the two-guy startup was recently acquired by Google therefore you know that it has a good seal of approval.
