Images of the Nokia 305, 306 and 311 mobile phones have leaked online, along with a user manual showing off features that seem similar to the Meego interface on the N9 smartphone.

If rumours are true, the Nokia 305 will be a dual-SIM handset with a two-megapixel camera, while the Nokia 306 will have the same specs but with a single SIM.

The Nokia 311 is expected to add WCDMA and WIFI connectivity, as well as increasing the camera resolution to 3.2-megapixels.

The Nokia 311 may also be known as the 'Sonic' version of Nokia's S40 handset, although that title has not been confirmed yet.

Nokia is expected to launch the range of S40 handsets in the coming months.

A manual written in the style of an airline flight instructions document has also leaked online, showing off many of the features of the Nokia 311.

Nokia posted an operating loss of €1.34bn (£1.1bn) for the three months to the end of March 2012, following a 50 percent drop in smartphone sales.
