Is anyone else sticking with their Bionic because you're grandfathered into Verizon's unlimited? I went to Costco and just inquired about upgrading, and he mentioned that sooner rather than later Verizon will force us off the unlimited anyway. He mentioned something about a 6 GB plan that won't cost me any more to switch to. I only typically use 5-6 GB anyway. Are any of you familiar with this 6 GB plan?
