Want to know about all the hottest features in the upcoming BlackBerry Z10? Well now you can, although it will help if you can speak German. German website TelekomPresse has posted a pretty extensive video showing off the BlackBerry Z10’s user interface, multitasking capabilities and its BlackBerry Hub messaging center. The video doesn’t show anything we haven’t seen before, although it has a lot of great closeups of the Z10 that show how compact and thin RIM’s (RIMM) new BlackBerry phone will be. The full video of the BlackBerry Z10 demonstration is posted below.
