Google has acquired telephone service GrandCentral, and has taken the service “invite only” as they incorporate GC’s technology into Google.
For existing customers, the service will continue largely unchanged. The big difference is that you’ll no longer be able to upload your own “ringback” tones, but instead can choose from ones Google has licensed.
Consumerist readers will be familiar with GrandCentral’s many spiffy features, as well as its ability to combine with T-Mobile’s 5 Faves program to form a sort of free calling Voltron. Consumers who are interested in signing up for the new Googlified GrandCentral can sign up for an invite.
