Well, it's finally here. Sort of. It's been a long and winding road for BlackBerry 10, and as has been RIM's way, the company continues to out new BB10 details just a bit at a time. As you may recall, we got a good look at RIM's original Dev Alpha hardware back in May, and were able to swipe our way through a good bit of BB10 a month later. It's BlackBerry Jam time now, though, and RIM gave us a more thorough look at the OS than ever before, and we got to see it running on a new Dev Alpha B handset. We couldn't pry loose any details about the hardware inside the new dev phone (other than it's got a BB10-standard 1280x768 screen), but we did get a few fresh facts about the software running on it. Once again, RIM reminded us that the software we saw was not the final version, but that shouldn't deter you from reading on past the break and seeing a video of BB10 in action.
