T-Mobile's roaming deal with AT&T has obviously already kicked in: Astute reader Klaus Ernst let me know several days ago that the New York Starbucks locations were offering an AT&T login on the gateway page. I lackadaisically tried this out yesterday here in Seattle. AT&T has a ton of roaming partners, so it presents an interface that lets you type in whatever your particular credentials are to gain access. With my Boingo Wireless account, I have easy access to Starbucks now. The screen below was captured on my iPhone at a Starbucks in Fremont, Seattle (otherwise known as the center of the universe).
