If you would like to upgrade one of your basic phones to a smart phone, you aren't necessarily forced to switch over to the share everything plan. A VZW chat rep told me otherwise. Reading some of the discussions at this site I found the following (Item #2):
The only thing that necessarily HAS to be done after June 28th, is people lose unlimited data if the extend or renew a 2 year contract, the share everything plan IS optional. The only people that are FORCED to be on the new share plan are new customers, everyone else is grandfathered in on their old plan.
