If you’re a Google Voice user and you’re not TechCrunch founder Mike Arrington (who was able to port his number into the service a long time ago), odds are pretty good you’ve prayed for incoming number portability at some point. And for years, your prayers have gone unanswered. Well, no more — Google has officially implemented incoming number portability as of Wednesday evening, and it is in the process of being rolled out to all users. Rejoice! To port your number into your Google Voice account, simply click on Settings in the top right corner, and then Voice settings. Now, on the phone tab next to your Google Voice number, click on Change / Port. Now click on “I want to use my existing mobile number instead” and follow the on-screen instructions to port your number. There you go — you now have 867-5309 as your phone number and $20 less in your pocket.
