Reader notes that AT&T has a simple giveway for using their network at no cost until Dec. 31: Klaus Ernst, a handheld Wi-Fi device aficionado, writes in to note that he spotted a link to get free access to the AT&T FreedomLink network over at JiWire's hotspot directory. Search on any AT&T FreedomLink location--that's the 4,000 UPS Stores, Barnes and Noble outlets, and other hotspots in their self-contracted network--and you'll get a link to a coupon. The coupon is good until the end of the year, and apparently allows unlimited use. (This excludes McDonald's locations, which are available to AT&T FreedomLink subscribers, but which are operated by Wayport under a separate agreement.)
(Disclaimer: I have a long-term relationship with JiWire on editorial and testing matters, and a small stock ownership in the firm.)
