Dell's Aero smart phone is now on sale in the U.S. for $99 with a two-year AT&T contract.
Dell has been selling similar phones in China and Brazil since late last year and has been promising a U.S. version since January.
The world's No. 2 personal computer maker, behind Hewlett-Packard, has been looking for ways to diversify its business as profit margins on traditional PCs have grown thinner and thinner. Dell also wants to stay relevant as more everyday computing tasks get done on smart phones instead of desktops and laptops.
The Dell Aero uses an older version of Google's Android operating system than many competing phones on the market today. Dell says it has done a significant amount of work adding features to the base Google system.
The Aero has a 3.5-inch touch screen and a 5-megapixel camera, and has photo and video editing functions built in.
