Review: Samsung Galaxy S 4 for Sprint

I live in NYC, and I use Sprint's LTE network all over the city with the exception of Staten Island, otherwise Bronx, Brooklyn, Manhattan, and Queens. I have even gotten LTE service on a boat.

So I don't understand why the reviewer was unable to test it out, unless its because he is not allowed to due to it not being official out, or the phone was set to 3G only in the settings.
