Actually in the past 4 days or so, there have been reports that T-Mobile is "refarming" some of its towers and there is now 3G support for iPhones in some parts of the northwest.
Also the iPhone 4s is a quad-GSM phone with HSPA+ support and so could conceivably, if I just mix and match acronyms, get 14M to 42M down on Tmo's network.
I am not sure of the magic behind this, but I believe it's the same as bringing over a quad band GSM Galaxy Nexus from Canada/Europe and putting it on Tmo's network, with the exception that the Nexus is carrier unlocked and the iPhone 4s is not. (I believe.)
