Ahead of BlackBerry's announced launch of its unique square-shaped in September, an alleged BlackBerry Passport review has surfaced online.

The review is by Czech website Mobilenet.cz (via GSMArena), which lists a variety of details about the BlackBerry Passport (codenamed Windermere) including specifications and features.

Till date, the Canadian smartphone manufacturer has revealed very few specifications of the upcoming BlackBerry Passport - it will feature a 4.5-inch 1440x1440 pixel resolution display with a pixel density of 453ppi.

The alleged BlackBerry Passport review mentions the smartphone will arrive in Europe in October at a price of CZK 16,000 (roughly Rs. 45,800). It goes on to say the BlackBerry Passport will feature Corning Gorilla Glass 3 protection for the display, which is in-line with the previous leak.

According to the review, the Passport is powered by a quad-core 2.2GHz Qualcomm Snapdragon 800 MSM8974 processor with Krait 400 CPU and Adreno 330 GPU paired with 3GB of RAM.

The smartphone is said to house 32GB of inbuilt storage, which can be further expanded via a microSD card slot (unspecified limit - the previous leak had indicated up to 64GB). The review says the BlackBerry Passport features a 13-megapixel rear camera with LED flash and OIS, as well as the ability to capture full-HD videos at 60fps. There are no details on the front camera as of now - though the previous leak had pointed to a 2-megapixel camera.

Interestingly, the BlackBerry Passport's Wi-Fi connectivity is said to only support the 802.11n standard, while the smartphone is also said to come with NFC and LTE connectivity. The review adds the BlackBerry Passport features a 3450mAh battery, measures 128x90.3x9.3mm, and weighs 195 grams. All these specifications appear to be in-line with the previous leak.

The Czech website's review of the BlackBerry Passport also states that the device feels sturdy and is easy to grip because of its soft touch build material. A unique feature of the BlackBerry Passport reported by the review is that the keypad can also act as a large trackpad. The review details a gesture command that enables users to quickly delete words by swiping left, though it hasn't detailed whether this gesture is for the trackpad, touchscreen, or in proximity to the device. The website also mentions that the handset is clearly not made for one-handed use.

The early BlackBerry Passport review also pictures the yet-to-be-launched smartphone alongside the Z30, Samsung Galaxy S5 mini and Nokia Lumia 1520. More images can be seen on the website. We'd like to remind readers however, that until BlackBerry confirms the smartphone's specifications and features, the above details will have to be taken with a pinch of salt.

The pre-registration for the BlackBerry Passport started earlier this month.

Interestingly, on Tuesday, the company's alleged 2014 roadmap for hardware and software was leaked, hinting at some upcoming launches as well as software updates. The leaked roadmap featured purported BlackBerry descriptions for new Affordable, Classic, Innovative, and Prestige segments, detailing them as 'Contemporary Yet Affordable', 'Powerful Yet Uncomplicated', 'Unique Yet Purposeful', and 'High Design Yet Functional' respectively.
