The biggest factor for you though should be the signal. Side by side here in Metro NY my AT&T 8310 has 4 bars, my TMo 8320 has 1. (Which i why it is now unlocked and will be used on AT&T)
Got to agree re: price differential - TMo is significantly cheaper across the board. But I am bewildered by your experience re: relative signal level between AT&T and TMo. For the last few years, we used Cingular/AT&T at work, and I used TMo for my personal line. I always carried both devices with me at all times. I live in central NJ, and work in NYC. When out of town, I'm anywhere from DC up through New England, but most of my time is in Manhattan, anywhere from Wall Street up through midtown (east and west) and up to about 186th street on the West Side.
In my experience in NYC (which spans many years), especially in the last couple of years, T-Mobile coverage in Manhattan has been excellent. The *only* place I don't have a good strong signal is in the subway tunnels (rumor is that Verizon has picocells in the NYC subways, but I don't know if that's true). Aside from that, TMo coverage in NYC has been superb for me for several years -- and the service has been far more consistent, with less outages (BB and otherwise) than AT&T. TMo customer service also blows away AT&T customer service.
I was also stunned at how bad AT&T/Cingular has been with billing on our corporate account. For the last 3 years, they have screwed up our corporate bill many times, billing us for accounts that we terminated a full year earlier, pleading ignorance, shifting us from one person to another when we demanded that they reconcile the problems and threatening to shut us off in the meantime. Possible that the problem also had to do with somebody at our end -- I really cannot say for sure, but from what I saw, it seemed that they were only interested in resolving the issues when we raised a huge stink about them.
Anyway - back on topic: I found, for example, that signal at Wall Street and vicinity was superb with TMo -- both on the street and inside office buildings. At 55 Water Street, for example, on floor in the 20's, I have a strong signal even when deep into the center of the office floor away from windows. In contrast, my friends with both AT&T and Verizon often find their signals fade in this spot. In midtown (East and West), I also have superb signal with TMo -- typically 4 or 5 bars.
BTW: I've had this experience with several devices, including phones from Sony Ericsson, Nokia and RIM/Blackberry.
Maybe there's a problem with your Curve? Or perhaps the SIM isn't programmed properly to pick up the right towers? I'm really surprised to see your experience so radically different from mine....
