Just received the update. Comparing my device the the Sprint variant...why is it that my device says boom sound Dolby audio abd the Sprint variant just says boom sound. Is HTC and or Verizon pulling a fast one. Remember Dolby is suppose to be for the m9. Could it all be a gimmick??? One thing is for sure, I will compare the m9 to the m8s audio output, when it releases. HTC thunderbolt was a big disappointment hope the m9 doesn't follow that path.
