I am a little confused. My Verizon phone was able to roam on GSM because they used TDMA. Tell it was shutdown. The phone recognizes it as Analog. If PCS has TDMA, It could be technically be used on GSM.

I'd doubt it, 3G data roaming on AT&T is a no go. There is no agreement for it (yet) T-Mobile could be deploying PCS 3G which would be an excellent idea, since they do have excess holdings in some places and need to start focusing on HSPA.
To put it simple (even if not on At&t) you are roaming on someone's GSM network because all iPhones lack T-mobile's 3G -1700 mhz data frequency.
To put it simple T-Mobile does not hide roaming carriers, not that there are so many that are in a native T-Mobile coverage area with 850 or 1900 HSPA. So unless the banner has been modified the 3G is on T-Mobile.
I didn't say he was roaming on AT&T, could have been any roaming partner. And also the OP never said what his alpha tag was while having 3G service. And finally, perhaps it was just a software glitch and he never actually had 3G service.
One things that's indisputable is that iPhone is not compatible with T-Mobile's 3G network, so whatever it was, it wasn't native T-Mobile 3G service.

Getting 3G "on T-Mobile" implies that it's "On T-Mobile's" network and not another carrier. How many GSM/HSPA regional carriers are out there on the 850 and 1900 bands that haven't been bought up? If T-Mobile is deploying PCS 3G which is of high likelihood it's very possible that this is what's happening. Also note in "some places". T-Mobile sells data cards and devices capable of PCS HSPA, so if they did deploy PCS HSPA there would be an instant increase in capacity and an offload on the AWS spectrum.
It's possible that it is a glitch, but AT&T or another roaming carrier? Nope.
You can get on Tmobile's 3G with the iphone 4S depending on where you are. The reason being is that Tmobile's 3G is now broad casted on two bands 1700 and 2100. basically if you are in an area where Tmobile's 3G is being sent out on the 2100 band then the iphone 4S will be able to pick it up because that iphone, and it's the only iphone, supports that band. i'm not 100% sure, but i believe you'll find most of the 2100 covered areas on the east coast.

Actually no, you need both bands in order to get T-Mobile's 3G/4G network. The only way OP is getting a 3G signal on T-Mobile is if T-Mobile is deploying PCS 3G to supplement AWS 3G.

That isn't true. TMobile uses 1700 MHz for the uplink and 2100 MHz for the downlink. There is no area where TMobile has regular 2100 access in the US.
