. . . provided Verizon will let me take an early upgrade, which they've done before (I've been a good customer for over 8 years now). I've had my HTC Thunderbolt for almost a year now, and while it's been a great smartphone, battery life is ephemeral at best. I even tried the trick of using an HTC Rezound battery (1620mA vs. the TB's 1400mA), but that gave only marginal improvement - 7 hours of very light use before I'm down to the yellow? Not good. I want to go back to the days where I charged my phone overnight and took it for granted that it would be good for an entire day, at the very least. So to that end, I have a couple questions: First, Verizon's price (with 2-year contract) is $299. On Amazon, however, it's being offered for $199. Is there a catch? Second, I'm currently grandfathered in under Verizon's unlimited 4G data. I won't lose that, will I? Anything anyone wants to share that will convince me to make (or dissuade me from making) this move would be greatly appreciated!
