Pretty much anyone within the contiguous US can upgrade from Gen4 to Gen5. The cost of the plans are listed on the following site, as well as the discount offers, but what the price would be, and what offers are available to you (depending on if you're in or out of your Gen4 contract), may vary. Your best bet is to call the number on the site to see what your offers would be. If you don't like what they offer you aren't required to upgrade.
