Getting online free of charge at Starbucks in the US

You know, that I love Starbucks and one of the reasons is FREE WIRELESS LAN. In the US it is a bit complicated to get wifi-access in the Starbucks stores, but this is how it works:

-get a free Starbucks-prepaid card in the store
-load it in the store with at least 5 US$ (you can use this completely for purchases at Starbucks)
-register the card online at www.starbucks.com/card (you have to use an US address-be creative)
-register for att wireless (the registration will direct you to this automatically)
-from then on you can use wifi for up to 2h a day free of charge in any US Starbucks

Have fun - I am posting this from a Starbucks in NY.
