Sprint If they can get the Network Vision going and soon, then they will be in a good place. But...the way they have handled the LTE launch has gotten a lot of people mad in the launch cities who can
t find a LTE signal to lock in on. That and there seems to be some software radio issue with the EVO LTE, locking on 4G for a second then switching back to 3G, that they already knew about before it was released and still haven't fixed that problem. Also you got the tower software issue that the Sprint engineers knew about and admitted to where the towers wouldn't report issues. They just assume people are going to wait until they fix it with Network Vision.
I am glad I went with Cricket. Maybe once Sprint get their act together, I might entertain going back but it feels damn good being on prepaid and much cheaper too.
