I get free wifi because I have AT&T Internet service at home. I have u-verse but I believe they offer free wifi to all their DSL customers too.
 
Last Saturday, I had to use my starbucks account to get into wifi, but today, it automatically connected to the attwifi at there. It worked fine without any need of entering my account info. Just like the iPhone.
