We would love to be able to tell everyone when we expect to start the beta, but it would put us in a bad position if we have to slip the date for any reason. That said, we expect to start the beta in the first quarter of this year. (2009)
The beta will start with a select few targeted users. Once we're certain the app is working as expected for those users, we will expand to more users with different devices on different wireless providers. So, if you are not chosen and you hear of other people who were chosen, do not be disappointed. You may still be selected as we ensure the app works in more and more environments.
