This is the biggest news about Google Voice since the company behind it, previously called Grand Central, was acquired by Google in 2007. They've integrated with Sprint. What that means is you are one of Sprint's 50 million U.S. customers, your Sprint phone number is now also a Google Voice number. And If you're already a Google Voice subscriber, you can use that number on your Sprint phone without the need for any software. Details are at google.com/voice/sprint . Here's how it works. If you are currently a Sprint customer, you can opt in to make that Sprint phone number your Google Voice phone number. This isn't number porting, Sprint retains control of your number. They simply tell Google when you make or receive calls, and forward that call to other phones if you've chosen those options. Google also takes over the voicemail for the phone, and long distance calls are completed by Google at Google's very low international rates . In other words, if you have a Sprint phone you can choose to make that a Google Voice phone as well. And get all the benefits of Google Voice, like having it ring to any phone you control, initiating and receiving calls from Gmail, hilarious voicemail transcriptions , etc.
