The service, which started life out as GrandCentral, acts as a unified phone number. It can be used to make free calls to the U.S. and Canada, to send free text messages and more. Its voicemail system can even bechecked by e-mail.
Now, after more than fifteen months of testing with invite-only accounts, Google Voice is ready for the masses.
As great as the service is, it hasn’t existed without controversy. Last summer, Apple was criticized when the company barred the Google Voice iPhone app from its App Store
. The battle over Google Voice was arguably the first shot in the current Apple-Google
war.
