I read that you need an invite, but when I googled it, I found a page to ask for an invite. I gave google my info and said an invite would be soon. Was that what I was suppose to do to get an invite or do I actually need to get one from a user? I'm a little confused now after reading this thread.
If you ask Google for an invite, it could take weeks or more likely months, if you get the invite at all. However, after you've been using Voice for awhile, they make invites available to you to share with others.
