I'm thinking about upgrading my Samsung Continuum to a Droid Razr. Verizon is offering the original Razr for free. I had a couple of questions first though. 1) How's the battery life on the razr? 2) If it's not good can you put in an extended life battery? I had to do this with my Continuum. I'd get 8-10 hours with the one that came with it. I get double that with an aftermarket XL battery. 3) Is JB the current release on the razr? I keep reading conflicting things. Some say it was leaked and only a few lucky folks got it. Others say that's the current version for the razr now. 4) Overall how happy are you with your razr? I've been dissatisified with the Continuum. It's still on Froyo and neither verizon or samsung have plans to ever update it. It locks up 2-3x per week too and I have to either pull the battery or reboot it with power+upVol.
