I just purchased and downloaded Documents to Go Premium. As part of the installation I have been asked to "Select Your Device Platform." I have an HTC Thunderbolt so I chose Android, but then I am asked to "Select Your Device." HTC Thunderbolt is not a listed option. The only HTC's listed are Desire, Dream, Droid ERis, Droid Incredible, EVO, Hero, Legend, Magic, and Tattoo. Why isn't Thunderbolt listed? What do I select that has the best chance of working on my Thunderbolt?
