with their recent special deals. They have some new 4G phones for only $99 with a 2 year contract. That combined with the double data deal and a $327 gift card I got from FiOS made me jump on the deal. They got me to dump my unlimited 3G plan with my HTC Incredible and get an HTC ReZound. Since I didn't know how long the double data special was going to last I figured I might as well get it now. Since a 2GB plan was not going to be enough. I surpassed that around every other my with my 3G phone. And without that incentive I would have stayed with my 3G phone.
Why would you dump unlimited for 4GB tiered data, on Verizon you can upgrade from a 3G to a 4G phone without losing unlimited data, all existing unlimited customers are grandfathered in, I'm on verizon's 4G network as well, and I think the Iphone factor and the LTE poor battery life as well as people waiting for an upgrade are all big reasons for slow adoption, it will improve it's a much better experience than old evdo
