Images of the new BlackBerry Curve 8520 ‘Gemini’ smartphone leaked for our viewing pleasure. The BlackBerry Curve 8520 features some new innovations from Research in Motion, including an "optical trackball" (so long sticky balls!) and dedicated media player buttons. The Curve 8520 has an updated look too: on the front of the device the LCD protector sort of extends down over the buttons for a more polished appearance; the perimeter of this new Curve is rubberized (rubber coated buttons) and the whole device has that swanky blacked-out look from factory. Despite the lack of 3G, all-in-all this is looking like a pretty nice extension to the Curve line.
