You can get free wifi at starbucks without any AT&T setup at home. The steps:

- buy a starbucks gift card ($5 minimum)

- register the giftcard online

- use the registration info when prompted when you connect to the network at SBUX.

- you must make at least one purchase each month on the giftcard, e.g. a tall coffee for $1.50.

- you can only use two MAC addresses on that card. Otherwise they'll lock your account, but you can call and get it unlocked.

- with said giftcard you also get free refills and free flavorings of some type too, even if you don't use the giftcard to buy the coffee in the first place.

I go to starbucks pretty much every day and that's how I get online there.
