BGR has screenshots of a BlackBery with a touchscreen using BB OS 6.0:
RIM has finally implemented system-wide kinetic scrolling with rubberbanding. This makes the experience a bit more fluid when scrolling through lists, web pages, emails, and the like. There is also multitouch system-wide, from the web browser to the photos application, and yes, pinch to zoom is in there.
All this over three years after the iPhone debuted.
