At&t began offering their high speed cellular 3G data network today in Lincoln. Much faster than the existing Edge data network, 3G allows wireless users to surf the web and download music and files at speeds up to 14.4 Mbits on the downlink and 5.8 Mbits on the uplink. This new service opens up a wide range of new capabilities for iPhone users who own the latest 3G enabled version of the popular handset. At&t had promised Lincoln and Omaha iPhone users that it would have 3G service in place by the end of 2008, effectively delivering the service in Lincoln a full month ahead of schedule.
