This MAY have to do more with Frontier, Routing and/or Location.
The fact it works for some and not others suggest its not a HTC issue.
The fact that there was Frontier issues, depending on your location during the connection update makes their system suspect.
The affect of any problem or glitch on a user would suggest poor programming and maybe not worth it. Its not good for company credibility or reputation, certainly not good for attracting new users. Think about if they post the issue on other forums making the game lame.
We know how to fix it, a new user less likely. We’re not worried about us.
Meh! We all mean well.
