Saya mau tau The BlackBerry Store dari BlackBerry. Jelaskan dalam bahasa melayu

In December 2007, it was reported that the first ever BlackBerry store was opened. While it is the only BlackBerry store currently in existence, it actually is not the first. There were three prior attempts at opening BlackBerry stores in Toronto, London, and Charlotte, but they eventually folded. The current location is in Farmington Hills, Michigan. 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 on the regulations of each service provider. There´s also a non-offical BlackBerry Store called BlackStore in Caracas, Venezuela, because of the big popularity that has the BlackBerry brand in Venezuela, especially in Caracas, making Venezuela one of the biggest BlackBerry consumers in the World.
