Back in April I wrote about Google Voice incorporating VIOP and using it over a phone with only a data plan, or over wifi, and not having a voice or text plan, similar to Clear's services. Then in May I wrote about how clear was considering making a product of their own that ran on a nearly identical concept. Well about a month ago, Google launched Voice through GMail. I've used it quite a bit and i love it. Now all they need to do is update the Google Voice app (Including multiple OS's) so it can take advantage of this capability.
