I have a HTC TyTn (quad band GSM/GPRS/EDGE 850/800/1800/1900 and tri band UMTS/HSDPA 850/1900/2100) and since AT&T's data speed now (since 3G iTards flooded in) constanly fucked up here (NYC) I'd gladly give TMO a try if I know they use 2100MHz here (I doubt though)... -- [BQUOTE=[user=bicker]]Waaaa waaaa waaaa. You just want what you want and don't care to factor in what is right or true. Your perspectives are un-American, and deserve far more ridicule than I'm prepared to pile on them. [/BQUOTE]
Both. A 3g 2100mhz device will NOT receive 3g from tmobile because it needs the 1700mhz band too. Called aws. I think it's 2100mhz downstream, 1700mhz upstream. It is special vs. the euro standard. The only 3g tmo devices are the ones they sell and 2 data cards sold by stelera wireless. That is all so far. No windows mobile, blackberry or sidekick.

You need both 1700/2100. One is the downlink and the other is the uplink (not sure which one).
Another reason they've been able to launch so many sites so quickly is because they actually have been building out the network and were just waiting for the government to clear AWS (which was overdue).
