Screw patience.

I (and most of us here) have been patient for far too long already.
I am not buying promises anymore. I am buying service. If Sprint has LTE service in my area in late September, I'll consider buying it. If not, we won't consider them....because we are buying LTE service and they can't offer it. It's the same reason that I won't buy LTE service from the kid down the street with a lemonade stand.
Keep in mind, even if they have LTE rolled out in DC/NOVA in that time, it will be something like 20% of the towers...with questionable backhaul. It will still take them a year or more after that initial rollout to upgrade all of their towers and backhaul. Thus, even with a rollout, you are likely to have poor to non-existent LTE service for almost the entire duration of your contract....and we are expected to also be patient for that INITIAL rollout?
VZ has 371 LTE markets as of today...as opposed to sprint's 5 (yeah, not buying them taking credit for nearby cities to get to 15...especially when some of those rolled of markets don't even have 20% of their towers upgraded).
Why have patience? If Sprint needs two years to get in the same ballpark as VZ, great, they can have it...I just won't be paying them during that time. I'll reconsider after my VZ contract expires.
That said, I'll stick with my earlier statement. If I can walk into a Sprint store in late September and get a phone that can get an LTE signal that very day outside of that store, I'll give them a shot. Otherwise, I am done screwing around.
