Casey posted this heads up about using Google Voice with your existing number and I must admit that seems more appealing than signing up for an entirely new number. I've signed up for Google Voice but really don't care to inform everyone I know that the phone number I've had for 10 years is now different. This seems like the best of both worlds.. I just wonder if it's advantageous as an iPhone user. Regardless, glad to know the option is out there!
