I couldn't see how to edit my earlier post about the govt/public sector discount. In any case, just wanted to point out that I currently have a Sprint Pre (that'll soon be replaced with the nexus s 4G), and the issue is not the Pre. Even Google Voice's blog page, look under FAQs, states that if it's not working for you, one reason could be that your phone is listed as a corporate account. I'd call Sprint and ask them to switch it to an individual account, but make certain that they'll keep your discount. I believe this is possible, as I was in the process of doing it when the stupid customer service lady accidentally transferred me to the business department; then i got fed up and just hung up and decided to leave my account alone.
