As we await the arrival of the rumoured BlackBerry Z10 at the end of January, little information has been shared about pricing. But according to a new leak, it will be\u00a0\u00a330 less than an unlocked iPhone 5.Engadget obtained an internal screenshot of the phone listed off-contract and SIM-free (unlocked) for \u00a3480 (or $750 USD)\u00a0at Carphone Warehouse. The model number\u00a0BLAZ10WHI matches up with previous leaks.\u00a0RIM is set to officially unveil its\u00a0BlackBerry\u00a010 operating system and the first two devices that will carry it on 30 January in several countries around the world.BlackBerry 10 and the BlackBerry Z10 have already been completely exposed by several leaks online. The\u00a0touchscreen Z10\u00a0- with\u00a0the BlackBerry\u00a0X10 being the Qwerty keyboard-touting phone of the launch duo - has a 4.2-inch display.
