Wow, only took them three years longer than they said it would take. I even went through a two year contract with Sprint starting in 2010 in which they told me that 4G would be in CR by summer 2011. That contract expired a year before they finally got 4G in CR, and I gladly became a Verizon customer.
For those of you thinking switching to Sprint is worth it - don't do it. It truly sucks compared to Verizon. I would much rather pay $90/month for a smart phone that can actually live up to its capabilities on the network compared to $75 for a smart phone on Sprint that is almost worthless when you're not on wifi.
That might be and to each his own...but I have been a happy customer of Sprint for a long time! Few problems...although Sprint gave me a "mini" cell tower that connects to my internet (which is pretty cool) and my phone works awesome at home. And I don't use it at work so I really have to say that I enjoy saving the extra money that Sprint allows me to save...
