Google finally made use of its acquisition of GrandCentral back in 2007 by releasing Google Voice.
One advanced feature is that it will turn the voicemail into text for you and then SMS text message you or email you the text of the voicemail.
Google Voice is in its pre-release form and will be available to everyone soon. If you want to know when you can use it, fill out this short form for Google, and they’ll email you.
