Just a few hours after Verizon Wireless confirmed the official release date for the HTC Thunderbolt (March 17th), the official user guide is now available for you to download. So for those who are up to the challenge, hit up the download link below to feast on the more than 300 page document. At least you will have something to do until the March 17th launch day. Then again, that’s not so long away anymore. Have Fun!
