Ok verizon decided to let me upgrade two months early. Which phone should I buy. Now they won't let me bill to account because I missed a payment in june. I have narrowed it down to: Galaxy Nexus Razr Maxx Rezound Main things are: signal strength, battery and will it be upgraded to jelly bean and last me 18 months til next upgrade? My thunderbolt is ok but definitely not as good as the original droid I had for over two years.
