Google Voice has just opened up its fantastic, feature-filled voicemail to any phone number (pending that you have a Google Voice account). This means you can finally free your voicemail from your mobile phone service provider.
Basically what happens after you scrounge up an invitation for Google Voice is that you can have your current phone number's voicemails routed through the Google servers and enjoy voicemail transcribing, archiving and straight-to-SMS (or email) forwarding features. As the promo video points out, this means that your voicemails, which belong to you after all, can go with you, even after you switch carriers. I think that some mobile phone providers might be a tad ticked off at Google for this move as it removes a major hassle of switching elsewhere. [Google Voice Blog]
