Sounds like it's only worth it if you're in an area with LTE. I have the 4s on Sprint out here in the wilds of northern NJ and I'm sticking with the 4s. Sprint blows, but it's cheap. I have 3 iPhones on a family plan and my total cost (taxes & fees included) is $169 a month. Data is unlimited unless you mean data SPEED. The speed is extremely limited, but only by the overall suckage of Sprint's data network.
I switched to the 5 from the 4S and was stoked on the hardware upgrade. I went from Sprint to Verizon and the minimal speed increase VS the extra cost of plan was not worth it for my family.
Took the VZN 5's back and am still with Sprint.
With the cash infusion from the SoftBank deal and Network Vision being implemented, I feel Sprint is in a great spot, and will have a superior 4G LTE network.
I bet you keep paying your bill though don't you? Darn terms and conditions. Get us all every time.
They will continue to wait a month because they can.
Guess what world ends in a month so it really doesn't matter.
