I know this post was awhile ago but I've noticed that LTE speeds in NYC have decreased considerably this year. When I first got my iPhone, I would regularly get 40Mps down and maybe 20Mps up, about six months after that the average was around 15Mps down and 8Mps up. Now, I'm lucky if a get 6Mps down and 3Mps up. Frequently, I get speeds well below that. What's up?
