In regards to your comment, "I don't know that apps are considered software", I have one question for you, Really? Now while you may argue your point, VZ Navigator and all the other garbage that comes "pre-installed" are most definitely considered software as they cannot be removed without rooting (just like the os itself). Furthermore, what would you consider them, hardware? 
Yes, this is Verizon's responsibility to fix. As the previous post stated, this is a contracted subscription with Verizon. Anyone that argues that point is missing the big picture. So, Verizon, I hope you're listening (I know, I know, they never do lol). Take this opportunity to make the situation right for "your" customers. Reboots mid-call and all of the other issues need fixed. Believe me when I say you have more to lose than HTC with this. HTC will come out looking like the hero, especially when they say that once they've released the fix it's up to you. Remember, we are YOUR customers, not HTC's. We purchased their handset with your software (that's right, you mandated and approved it) and PAY dearly for your services. So, guess what, this is YOUR problem, YOU own it. Stop the blame game and step up to the plate.
Not to get ahead of myself here, but I do believe that some form of reimbursement is necessary to owners of the Thunderbolt. But, since I know you, Big Red, VZW, The Fastest 4G network blah blah blah, have your hands full, fix the issues first and then satisfy your customers. We have tolerated missed appointments, dropped business calls and horrendous customer service (thank God it wasn't every time I've called in or I would be sitting in a padded room somewhere).
