I got tired of the constantly trying to figure out the better deal and worrying about unlimited data and everything else. I actually used my upgrade on Verizon this weekend and changed to the share everything. I chose a data plan that's fine. My phone has been broken for months and everything was downloaded over cellular and I still barely reached the data max we have on the new plan. I just don't care anymore.
You could have easily sold your unlimited line for $300.
