BlackBerry's R10 smartphone has been glimpsed in what is said to be a leaked photograph of the device, Digital Spy said.

The handset is said to be a budget alternative to the BlackBerry Q10, combining the same physical keyboard with scaled-down hardware specs.

The R10 appears to sport a similar form factor to the more powerful Q10, but has a distinctive red bezel and slightly different keypad design.

BlackBerry will launch the device during the third quarter of the year with a price tag somewhere between $300 and $400 (£192 and £257), according to pocketnow.

The R10 would be the third device to come with the BlackBerry 10 operating system pre-loaded, following the touchscreen Z10 and the Q10.

BlackBerry released the Q10 in the UK last week.
