Nokia looks set to unveil the latest generation of its Lumia Windows Phone handsets.

A brace of rumours suggest that the new devices will be unveiled in early September.

According to Bloomberg, Nokia will show the first devices on 5 September, ahead of the likely 12 September release of the iPhone.

The unveiling will be made at the Nokia World conference, Bloomberg said.

Citing "a person with knowledge of the matter", Bloomberg said that the Windows Phone 8 handsets will be announced at the invitation-only conference.

NOKIA: VP of design on how Nokia might just be winning the design war

Nokia's Lumia 800 and 900 devices won plaudits on their release for their bold industrial design - but have not yet proven to be a hit with customers.

In its recent earnings announcement, Nokia said it sold four million Lumia smartphone devices, up from two million last quarter.

But it lost around $1bn overall because sales of its other phones fell quicker than the growth of its new lines.

  • Nokia 1011 (1992)

    Named after 10 November, the date it launched, this was among the world's first GSM mobile phones. Oddly enough, you could receive text messages but not send them.

  • Nokia 2110 (1994)

    The 2110 featured a 99-number phonebook, and a two-way scrolling control which meant you could actually navigate them. It was also the first phone with the signature 'Nokia' ringtone. You know the one... It was based on Gran Vals, a guitar piece by the 19th century Spanish composer Francisco Tarrega. Over time it was also highly annoying.

  • Nokia 8110 (1996)

    The Nokia 8110 was the first slider phone and was featured in the Matrix, resulting in a generation of slick idiots pretending to be Neo when picking up calls from their mum.

  • Nokia 9000 Communicator (1996)

    Nokia claims that was the 'world's first smartphone'. That might be pushing it - but it certainly pushed the boundaries. It had a full QWERTY keyboard, a 24 MHz i386 CPU, could be used horizontally or vertically, and could send a variety of messages - including faxes.

  • Nokia 5110 (1998)

    The 5510 was one of the first phones with a replaceable cover - and also one of the first to feature Snake. Which, kids, was a game in the olden days which drove. Us. Mad.

  • Nokia 7650 (2002)

    The 7650 was promoted in conjunction with the film Minority Report, but was actually fairly futuristic for its time. Beyond its experimental looks, it came with Nokia's first full colour screen and a built-in camera. This phone made Nokia the largest manufacturer of digital cameras in the world, the company claims.

  • Nokia 7600 (2003)

    The notoriously awkward, and now notoriously awesome 7600 featured a teardrop design, and a fabulously difficult to use interface.

  • Nokia 1100 (2003)

    The 1100 is one of the best-selling consumer devices ever made - 250 million have been shipped worldwide, largely in the developing world, due to its sustainable design, cheap price and built-in flashlight and radio.

  • Nokia 7280 (2004)

    Alongside the 7600, the 7280 is one of the weirdest phones ever produced. It featured a screen that faded to a mirror when it was inactive and used a Navi-spinner in the place of a keypad.

  • Nokia N93

    Just look at it.

  • Nokia 8800 (2005)

    The 8800 was a self-consciously premium device which featured a brushed-metal body, fine-pitch glass and ball-bearings in the slider. You probably weren't able to afford one.

  • Nokia Lumia 800 (2011)

    The Lumia 800 and 900 are Nokia's flagship Windows Phone 7 devices. They've since shared a gold award from the Industrial Designers Society of America, and are widely seen as - in industrial design at least - among the most beautiful devices currently on sale.

  • Nokia Lumia 900 (2012)
