RIM is set to officially unveil its BlackBerry 10 operating system and the devices that will first carry it on 30 January in several countries around the globe. However, the event will now be like a date with a famous porn star, there's very little else to see.

We've had more leaks than a woollen canoe when it comes to the new BlackBerry devices, but there has always been an air of mystique around certain aspects. Until now.

Austrian website Telekom-presse.at has completely blown the lid on the phone formerly known as the BlackBerry London or L-Series. It is now simply the BlackBerry Z10 (as rumoured a while back), and the site professes to have had one in its grasp long enough to give it a full review.

This is the touchscreen device - with the BlackBerry X10 being the Qwerty keyboard-touting phone of the launch duo - and its display is 4.2-inches. It's not Full HD, being only 1280 x 768, but is powered by a dual-core 1.5GHz OMAP 4470 processor with 2GB of RAM.

Storage space is restricted to 16GB, with the new BB10 operating system taking up 0.6GB, but it can be expanded through the use of a microSD card. A 2100mAh battery will last more than a day before charging, claims the site.

The Z10 measures 129 x 65 x 8mm with a weight of 125g. Its camera is 8-megapixel and the phone requires a micro SIM, like the iPhone up to 4S or Samsung Galaxy S III. The front camera is of the 1.9-megapixel variety.

Telekom-presse has shot some test video with the rear camera and reports good results. And says that even in poor lighting conditions, it is comparable to the iPhone 5 or Nokia Lumia 920. As those devices are worlds apart in terms of performance, we'd take that with a pinch of salt.

There are plenty of more revelations in the full review, including good reports of the voice control application - RIM's answer to Siri - but we'll wait until we get the device here at Pocket-lint to delve any further.

It will be interesting if RIM has something up its sleeve to bring out as a genuine surprise now. At least it seems to have a very decent phone on its hands.
