Brian Jepson reviews the Sony Ericsson EDGE card to the nth degree, including configuration advice and photos: This in-depth, multi-page review at Jiwire (our content partner) tells the results of Brian's real-world testing of EDGE service over AT&T Wireless's network in several cities, provides an explanation of how EDGE works (and why performance might vary), and is fully illustrated with screen captures and photos.
Brian also provides the information you need to use the card with Mac OS X and Linux, which aren't directly supported by Sony Ericsson. A small download, a few code changes, recompile, and voila! You've got high-speed cell data on unsupported computers.
While $80 a month may seem high for a consumer-level price, for business people who need ubiquitous data access, EDGE is really the fastest best option when it works. By January 2005, Verizon Wireless will have its 1xEvDO in potentially dozens of cities, while AT&T Wireless should have debuted UMTS in four or five towns.
