It's a little over a month until BlackBerry 10's official introduction, but that hasn't stopped leaked screenshots of the OS from circulating on the web. Some folks on the Tinhte Vietnamese forums, which also revealed hands-on video and gallery of the BlackBerry 10 L-Series, have just released pictures of RIM's revamped phone UI. Most notably, the images provide a sneak peek at a new "BlackBerry Hub" all-in-one message center along with an intriguing voice interface that reminds us a lot of Siri. We also get a preview of how apps like Twitter, Facebook and Foursquare will look; unsurprisingly, they seem pretty similar to their Android and iOS cousins. It certainly looks as if the redesign is a complete overhaul rather than just a quick paint job, but we won't know the full details until we see it for ourselves early next year. Until then, head on over to the source to get an early look at what could be RIM's savior.
