BlackBerry Curve 9230
New operating system
The Curve 9320 comes with the latest edition of the BlackBerry operating system: BlackBerry 7.1 OS, which supports features like Mobile Hotspot and wi-fi calling. It's undoubtedly the slickest version of the BlackBerry OS yet, but in our opinion it still lags behind the latest iterations of Android and iOS. That's also true of the number of apps available for the phone: the BlackBerry App World simply doesn't have the range or depth of software found in Google Play or Apple's App Store.
