More details are now available regarding the upcoming BlackBerry Passport smartphone, as a promotional video has leaked online revealing some of its specs.

BlackBerry has already teased its new Passport handset, but didn't offer many details when it comes to the device's specifications. Nevertheless, little remains secret in the tech world, as various leaks always reveal some info ahead of the actual launch.

It's no different with the BlackBerry Passport, as the device now stars in a new video that offers a glimpse into what the smartphone will bring to the table. The footage was spotted by CrackBerry and seems to be a promotional video for the handset courtesy of UK retailer Carphone Warehouse, as its branding appears in the video.

We already knew that the BlackBerry Passport will sport a square design that makes it look quite bulky, not because it's the biggest smartphone out there, but because it's wider than we're used to.

In terms of specifications, the video reveals that the Passport will sport a 10-megapixel rear camera. Previous rumors have also claimed that the handset will come with a 3.7-megapixel front shooter.

Earlier reports also indicated that the 4.5-inch display on the BlackBerry Passport will have a resolution of 1440 x 1440 pixels, but the video from Carphone Warehouse reveals that the smartphone will actually have a Full HD display (1920 x 1080).

The BlackBerry Passport also marks a return to BlackBerry's roots with its QWERTY keyboard, albeit it has a three-row layout, with numbers and symbols likely hiding behind a function key. It's worth pointing out that this keyboard is also touch-sensitive, which means that it can also serve as a touchpad. The video also gives us a glimpse into the company's new virtual assistant, aptly called the BlackBerry Assistant, which is BlackBerry's answer to Apple's Siri, Google Now, and Microsoft's Cortana. Lastly, the promo touches on the phone's design as well, highlighting that it's made of stainless steel, which is stringer than aluminum, and also makes it look more stylish.

The video doesn't reveal much else, but previous rumors indicated that the BlackBerry Passport will pack a quad-core Qualcomm Snapdragon 801 processor under the hood, clocked at 2.5GHz and paired with 3GB of RAM. The handset is expected to come with 32GB of internal storage capacity.

The BlackBerry Passport is expected to make its official debut next month, probably at the IFA 2014 trade show in early September. Some reports hinted at a Sept. 12 retail launch for the device, but it remains unconfirmed at this point. We'll keep you up to date as soon as we learn more, but check out the video below in the meantime.
