I noticed it as well. They had both the T-Mobile and AT&T signals at the one near here. I was in the drive-thru, so I didn't exactly mess with it, but they definitely had both signals. I'll have to go in sometime and see what the deal is.
So, what, just enter your number and go? Is there a cap or limit on time used, because I can sit in a 'Bucks sipping on a coffee for an hour...way cool though, kind of makes life that much better for us iPhoner's
@touchyphone Yeah, you just enter the phone number. I have been at Starbucks for a while (more than 2 hours) and I just had to re-login sometimes. I wasn't consistently on the iPhone though.
