Still kicking with my Rezound. Still like the phone but of course battery is sucky, and getting worse with age (have had it for a year and a half).
I'd root the phone, put a solid ROM on there like EclipticRez version 8 and enjoy your final months with it before shooting yourself in the foot by going to BB.
Been on my Rez almost 2 years now (thanks Verizon for moving back my renewal date 4 months too - seriously?). Been rooted most of the time and just this week jumped from Newts OneXxx to EclipticRez v9 - solid rom so far.
Rez is my 3 rd straight htc phone. Anyways, had some interest in seeing if Verizon would get the htc One but after seeing how htc phones on Verizon don't seem to get any updates or timely ones, where other phones got jelly bean, etc, and hearing this week that a bunch of htc executives jumped ship, I'm seriously leaning towards the Galaxy S4 (ideally a 32gb version since the 16gb is bloated 1/2 with bloat ware and big OS).
Galaxy s4 is more predominant and has users on all carriers so will be supported. I'll try holding off a few more months before calling my corporate rep, and see what comes out.
But also not too happy with Verizon shafting customers with not having good selection of premium phones, messing with our unlimited data, messing with phone price subsidies,etc...
