The Z10 is BlackBerry's best chance to compete against the iPhone and Android devices. It comes with a 4.2-inch screen, which is smaller than most Android phones but slightly larger than the iPhone's screen. It also looks strikingly similar to the iPhone, and will be available in two colors: black and white. BlackBerry decided to keep things simple and is only offering the phone with 16 GB of storage, but the memory can be expanded up to 32 more gigs with the help of a microSD card.
