Wow, that's sad that a Sprint store would do that. Why can't they just be honest for a change? I know that they love their commissions for selling phones, but for crying out loud, don't resort to lying like they did for the WiMax rollout just to make a sale.
If the backhaul isn't ready then there is no reason for them to turn the LTE on. Why give customers the same cruddy data on LTE as they have for legacy 3G sites? I sure wouldn't want that.
