Google has added a new feature to their maps. When you search for a generic keyword and location, the phone numbers are listed as always. Now you can simply click on the call button and type in your phone number. Google will then call your phone with the business number that you are trying to connect to as the caller id. When you pick up, it will then connect to the business. There is no charge or long distance fee for this, however cell minutes will apply. You can check out the official google blog post at:
