In Short

The BlackBerry Curve 8900 was a big upgrade from the Curve 8300. Unlike the Bold 9000 it lacked 3G, but had Wi-Fi-calling enabled. Stylistically, the Curve 8900 was a slight departure from previous BlackBerry devices thanks to its solid black trackball, which was later used in the BlackBerry Tour 9630. The BlackBerry Curve 8900 was released February 2009.
