Free AT&T Wifi at Starbucks
Lifehacker tells more about AT&T offering free wifi to iphone users:
To masquerade as an iPhone, you'll need to tweak your browser's user agent, which web sites use to identify your browser when you connect to the site. In Firefox, you can install the previously mentioned User Agent Switcher. In Safari, you can select the iPhone user agent through the Develop menu (which you can enable by navigating to Preferences -> Advanced and checking "Show Develop menu in menu bar." Likewise, Opera has user agent switching built in. On the non-Safari browsers, you'll have to manually add a new iPhone user agent like so.
I'm going to try this with my mum's iphone number. No, you gits, I'm not posting it.
