It was in May at RIM's 2012 BlackBerry World event that RIM started distributing an unrefined BlackBerry 10 prototype, codenamed Dev Alpha A, to developers. Shortly after, details of a more hardware-refined Dev Alpha B device were leaked on Twitter before making its official appearance a month later in September. Both devices are full touch-screen devices; the Dev Alpha A device houses a 4.2-inch 1280 x 768 pixels touch display, 1GB of RAM, 16 GB of internal storage, a microSD card slot and a dual-core ARM Cortex-A9 or better chipset inside. Currently, over 7500 of these devices have been seeded to developers in the hopes that a large number of apps are refined and ready at Jan 30th's BlackBerry 10 launch.
Of course, the L-series full touchscreen smartphones are not the only upcoming BlackBerry 10 devices; the N-series keyboard-armed cousin is set to round up the equation for those who prefer typing away on physical QWERTY keyboards. To ensure that apps run properly on a phone with a drastically different form factor, RIM will be issuing the Dev Alpha C QWERTY device to a selected pool of developers.
Nothing much is known about this device at the moment, save for the fact that it will house a "square touchscreen with a resolution of 720 x 720 pixels", according to Alec Saunders, VP of Developer Relations & Ecosystem Development. Otherwise, the upcoming N-series devices will definitely house a bigger touchscreen than previous BlackBerry devices. To further complement a robust developer environment, the final BlackBerry 10 Gold SDK will be available for download on 11 December, ahead of its official launch.
