You know the drill — grab yourself a spoonful of Morton’s and get ready for another supposed leak of a gadget. This time around, you’re looking at what’s claimed as being one of Research In Motion’sBlackBerry 10 “Development Alpha” devices that’ll be handed out during next week’s BlackBerry Jam — just like the company promised a month ago. Images of the device first surfaced over at Crackberry’s forums and, as the site points out, the touchscreen candy bar seems to share its design DNA with thePlayBook. Keeping in mind that it’s likely to remain a testing device for devs, don’t bank on it ever hitting store shelves. That said, we’re now curious how pivotal a roll RIM’s famous tactile keyboards will play on its next-generation phones — if any. Head over to the source links below if you’d like to catch more photos from Mr. Blurrycam and extra information in the meantime.
