Where T-Mobile provides 3G service for older iPhones

T-Mobile iPhone 3GT-Mobile announced today that it’s getting the iPhone. But in a practical sense, it’s “had”  that smartphone since it kicked off a network “refarming” effort last year to provide 3G and HSPA+ 4G service on the 1900 MHz frequencies used by the iPhone 5 and older AT&T-specific models, then started marketing itself as a better option for unlocked iPhones. Before today’s news, the carrier said it already had more than two million unlocked iPhones on its network.

T-Mobile’s Web site, however, doesn’t get around to identifying all of these iPhone-friendly markets–an important detail, since without it you’re stuck with slow 2G “EDGE” data service. (6:59 p.m. Engadget reports that new-production iPhones, T-Mobile’s own model included, will support a wider range of frequencies. I’ve revised the title to reflect that.) T-Mobile’s coverage map doesn’t break them out, and a FAQ page only says “Check at your local T-Mobile store for network status in your area.”

(The screen shot above comes from the iPhone of my friend Paul Schreiber, who’s been keeping me updated on where he’s seen 3G service.)

So I asked a company publicist and got this reply:
