The BlackBerry Curve 8300 is a series of BlackBerry smartphones developed by Research In Motion. Introduced in 2007, the Curve continued the "consumer-oriented" philosophy of the BlackBerry Pearl and 8800 series, including robust multimedia features and a high-resolution built-in camera.
As is customary for BlackBerry devices, the 8300 series consists of several models offered by different wireless providers, supporting that provider’s network along with specific services. The base 8300 model is a GSM/GPRS/EDGE handset, to which the 8310 adds GPS capability, while the 8320 excludes GPS but includes WiFi connectivity.
The 8330 instead operates on CDMA2000/EV-DO networks and includes GPS; the 8350i operates on the iDEN network and includes GPS, WiFi, and push-to-talk functionality.
