The 850MHz is working good in NYC.

I receive reasonable reception on the street and in my apartment. Sometimes the signal is better in one room than another, but overall, I have not had too much trouble receiving or making calls. At times, if I receive a call from someone who has an AT&T phone, the call gets dropped or the signal is bad, but I think that is on their side. Overall a 3 out of 5.

I've had T-Mobile for 1 year and reception is terrible in my apartment. I have to place the phone against the window, and even then I get one bar and constantly lose the connection.

Weak coverage -- signal usually only two or three bars, sometimes as high as 4. In almost every call, reception will eventually become spotty and audio will drop (typically, person on other end can hear me, but I can't hear them). Very annoying.

Good reception in apartment and on street. Few dropped calls.

Even though I have a few bars, no reception whatsoever for 1 1/2 weeks now. I live near this intersection unfortunately, so no reception in my apartment. If I walk down bway to 95th I can get a signal.

Lately the Cingular service has been horrible in my house. Judging from the comments, I should have never gotten Cingular in the first place. I think I'll switch to Verizon or AT&T. The only thing good about Cingular is its marketing!

3 bars on both the Uptown and Downtown side of the 103rd St. and Lexington Avenue Subway! Call was not dropped or lost, even with trains roaring past.

Verizon has never given me less than 5 bars whether in my apartment or on the street. Works great all around.

Works nearly as well as Verizon near Columbia's campus.
