No issues in NYC with T-Mobile, there is pleanty Of T-Mobile work going on in the tri-state area lots and lots of overtime( most are working 7/10s) T-Mobile is far from running out of money.You are lucky as you are now using their latest LTE offering which is very fast as you outline. I do see very fast LTE speeds here in NJ where they have a good LTE signal and sometimes it's even fast than AT&T which is cool. What's not cool is that overall their network in NJ is still poor. I mean lets look at one particular scenario. Iphone5S main road LTE service good signal, enter a small lot with small stores and you have a 4G signal outside, enter a small barber shop and as soon you sit down (close to the door) you have no service. Play with your phone (airplane mode, or reboot phone) and you now have 1 bar and an unstable 4G signal with slow or no data connection. Things like this really bother me. Also you read a lot of scary stories about indoor coverage specially in buildings in a major city like NY. I'm sorry but this is not Afghanistan, Tmobile you are not trying prove service up in the isolated mountains.
This was my third try, I just cancelled today, tested for 6 days. I do see improvements overall but right now they have a big issue with iPhones specially the 5S where the signal bounces and fluctuates all over the place (only happens on their network, AT&T is rock solid everywhere). Maybe I will try them again in a few months if I hear they have made real investments and implemented those proposed MIMO antennas and migrated the remaining old EDGE towers but I think all those things are going to take a long time to implement.
On the money issue, right now they appear to be having money problems. That is why they were looking to sell some stock recently, they were also trying to buy some spectrum from Verizon which will cost a lot of money. The failed AT&T merger gave them a boost with all that money they got from AT&T but it appears they already spent it all and what you see now might be what you get for a while.
I want them to succeed but they also need to make some changes to help themselves. Build a damn application and a platform like AT&T has (Mark The Spot) where customer's can easily report services issues from anywhere at any time and send Tmobile valuable/accurate data they can use to better their network. There are many small little things they can do without having to spend a lot of money but right now they just don't have the systems in place and perhaps Engineers with the experience necessary to make things happen.

I get LTE also and see it in a lot of areas in NJ (Parkway, Turnpike), it's just the other areas where the iPhone just locks onto the EDGE signal that really sucks or the areas that have very poor signal and you can't get usable service. With AT&T everywhere I have been I have either LTE or 4G, even underground in basements!

ATT sprint and Verizon are are slow, work may pick up in the spring. Although att is doing lots of in building cell infrastructure in NYC.
