The free AT&T Wi-Fi that iPhone users were enjoying at Starbucks last week seems destined to be expanded (all AT&T Wi-Fi hot spots) and made permanent for those using an iPhone on the AT&T network. Several users spotted an update to AT&T’s iPhone plan which clearly states:

To use iPhone, you’ll need to sign up for a 2-year service agreement. Plans start at $59.99 and include Visual Voicemail, Unlimited Data (email and web), 200 SMS text messages and access to AT&T’s more than 17,000 Wi-Fi hotspots, including Starbucks* all for use in the U.S.
*Wi-Fi available at U.S. company operated Starbucks locations equipped with a hotspot.
