Will AT&T GSM Improve in NYC? I live in NYC and I use AT&T GSM. In Manhattan I get a decent signal most of the time but when I travel into Brooklyn the signal is terrible with lots of dropped calls and the fact is that even in Manhattan I get a poor signal in certain areas along with the dropped calls. What I want to know is will AT&T GSM improve here in NYC or is this the best it's going to get? Is AT&T GSM still putting up towers through out NYC (Manhattan, Brooklyn, Queens, Bronx)?
