The Blackberry Store

In December 2007 a BlackBerry Store opened in Farmington Hills, Michigan. While it is the only BlackBerry store currently in existence, it actually was not the first. There were three prior attempts at opening BlackBerry stores in Toronto, London, and Charlotte, but they eventually folded. The store offers BlackBerry device models from AT&T, T-Mobile, Verizon, and Sprint, the major U.S. carriers which offer smartphones. Employees are trained not only on the BlackBerry devices themselves but in the practices of each service provider. There is also an unofficial BlackBerry store called BlackStore in Caracas, Venezuela, because of the BlackBerry brand's popularity in Venezuela, especially in Caracas and Maracaibo, making Venezuela one of the biggest BlackBerry consumers in the world. There is also a BlackBerry Store in the Atlanta airport.
