1. Network Vision/LTE deployment will not begin in your market until some time in 2013. 2013 market schedules have not been finalized yet. Should later this Fall. Upgrades shown at network.sprint.com are not Network Vision related, but rather are maintenance upgrades to their legacy system.
2. If you use WiMax heavily, you may want to hold off on upgrading until LTE deployment starts in your area. Unless you find 3G to be acceptable where you go. Currently, Sprint LTE devices only support LTE on 1900MHz. Whereas, some time next year, Sprint LTE devices will also support LTE on 800MHz (Nextel frequencies).
