Just a quick update for the Westchester folks.
I am getting LTE on my Galaxy Nexus in North White Plains by the train station and I'm lucky enough that my home is within range. Speeds on LTE have been between 5 to 9MBps download and 2 to 5MPps upload. If these speeds stay consistent I will be very happy coming from terrible 3g of 0.07MBps - 0.3 MBps on a good day.
