This may be common knowledge and don't know if it's nat'l/int'l but I was in NY based Starbucks a bit ago where I'd normally found a couple of free wireless cells for Internet. Today they weren't up but I hit the ATTWIFI and got the ATTWIFI/SB portal page. I guessed at a 'guest' account and put in starbucks and starbucks in both fields and got on.
Passing along should you be in SB and need Internet
