BlackBerry Curve is a model of entry level smartphones created by Research In Motion since the year 2007.

The BlackBerry Curve model was released in 2007 with the Curve 8300 series. The Curve brand name continued the "consumer-oriented" philosophy of the BlackBerry Pearl and 8800 series, like robust multimedia functions and a high-resolution included camera.

As usual for BlackBerry phones, the 8300 series consists of numerous types supplied by various wireless providers, supporting that provider's network along with certain services. In total 5 variants ended up released; 8300, 8310, 8320, 8330 and 8350i.

CNET rated Blackberry Curve 8300 an "Excellent" qualification. However, she discovered the Curve 8300's absence of 3G and Wi-Fi as lackluster. Also disappointing was the cell phone's lack of video-recording capabilities. Phone top quality was decided to be disappointing and calls sounded hollow on the Curve 8300. Even Though the 8300 as initially released lacked Video Clip Recording and Voice Be Aware Recording, these features have been provided with the Blackberry OS 4.5 release.
