Images of upcoming BlackBerry smartphones leaked online

New images apparently showing upcoming Blackberry mobile have been leaked online.

If genuine, the images show a straight keyboard similar to the one seen on the Torch model.

The photos were first revealed by CrackBerry.com, via Chinese site CNBeta.

According to the Daily Mail, the site reported that the latest image shows the BlackBerry 10 N-Series, which is rumored to debut with a touchscreen L-Series phone next month.

The device's operating system, however, still remains a mystery, as the phone is turned off in all the leaked image, the paper said.

Manufacturer Research in Motion (RIM) is still more than a month away from unveiling the next generation of the BlackBerry.
