RIM has been a pretty leaky sieve lately, what with all the news and hardware shots of their apparently upcoming slider device spilling out, but has someone accidentally let BlackBerry OS 6.0 out of the bag? According to BBLeaks you're looking at two screenshots of RIM's next-gen OS, and one of their best tipsters reckons they're legitimate.
Screen resolution is in line with a Storm or Storm2 style touchscreen device, and the buttons certainly look to be sized for finger input. That would also fit in with the BlackBerry slider - codenamed "T" or "Talladega" - which is expected to have a large touchscreen along with its pull-out QWERTY 'board.
RIM also look to be playing with the idea of using homescreen widgets, which would be a significant departure for the company. The BlackBerry faithful are already poring over the two images to see if they a) look real, and b) look suitably enticing, though comments already heard include the fact that the whole thing looks "too busy" for their liking.
Update: BGR are throwing their hat into the virtual ring, and saying that they've been told the screenshots are actually mock-ups that RIM had made for their MWC presentation. They've also heard that RIM plan to skip BlackBerry OS 5.2 altogether, and jump straight to OS 6.0.
