Just spent a while with Sprint tech support. No one had any clue and the the tech support guy kept insisting the Google Voice FAQ was wrong and that I needed an Android phone. Sprint really needs provide some clarity to their staff.
I also have a corporate discount, which is why I guess it's not working, although the account is in my name and the phone is not a corporate phone. Would've appreciated that condition being in the press release or easily accessible. Looking forward to this condition being lifted.
