Rumour: iPhone nano being developed by Apple

Apple could be developing a budget iPhone in order to ward off competition from Google Android handsets.

A prototype version of a smaller, cheaper Apple handset than the iPhone 4 is said to exist, although this is no guarantee such an iPhone will ever make it to market.

The mysterious little iPhone is apparently a third smaller than the iPhone 4, with no home button on the front of the handset, which certainly sits well with rumours that Apple is aiming to do away with the button on all iOS devices.

1,000 workers walk out on Nokia after Microsoft announcement

Nokia has had a day to end all days today, with news that the company announcing it is ditching Symbian in favour of Windows Phone 7 prompting 1,000 of its employees to walk out.

This is according to Finnish newspaper Helsingin Sanomat, which is reporting that workers are protesting with their feet at Nokia's Oulu and Tampere offices.

If the reports are accurate then this equates to a quarter of the workforce based at the two offices.

Rumour: Apple to expand iPhone 5 screen to 4 inches

Following persistent rumours of plans for a smaller, cheaper Apple iPhone nano, the latest Apple rumour this week is that the Cupertino-based tech giant is planning to release an iPhone 5 with a larger, 4-inch screen.

Details of Apple's next gen model reportedly leaked from component suppliers via Digitimes suggesting that Apple will release a larger-screened iPhone in order to compete with the growing threat from Android in the 4-to-7-inch smartphone market, such as Samsung's' Galaxy S and Google's Nexus S.

First shots of Nokia Windows Phone 7 concepts emerge

Photos of the concept handsets, believed to be the work of the new Microsoft and Nokia partnership, have emerged less than 24 hours after the deal was rubber-stamped.

Engadget is touting a pair of images which its claiming to be early mock-ups of a Nokia-manufactured handset running the Windows Phone 7 operating system.

The brightly-coloured phones boast full touchscreens with some Nokia design hallmarks and would add credence to Steve Balmer's claim that both companies have already been working together on devices.

iPlayer links up with ITV, Channel 4 and Five

The BBC has started integrating non-BBC channels into iPlayer, hoping that consumers will use the site as a landing page for other on-demand services.

Back in May it was announced that the iPlayer would begin to link to non-BBC channels and nine months later it has given birth to this 'sharing the link love' idea.

Now don't get your hopes up that you can now watch ITV content on the iPlayer, but you can search for on-demand ITV channels and they will appear on the iPlayer, with a link out to ITV Player.

Panasonic HDC-SD900 review

If you have the money, and also the need, for this level of 3D-ready Full HD camcorder then the Panasonic HDC-SD900 has to be near the top of your shopping list.

Panasonic TX-P46VT20B review

Anyone interested in 3D is advised to think larger than 42-inches. Panasonic's 46-inch TX-P46VT20B, therefore, has the potential to be a real winner

Sony BDP-S470 review

Sony has made one of the most impressive BD players around. Its compatibility with almost any disc is excellent while the pictures it delivers are equally spotless.

Panasonic HDC-SD90 review

This is almost the complete camcorder. It's hard to see, for the sub-�500 price, how you could reasonably ask for more. Watching our test footage played back, even mundane shots are imbued with an almost-tactile quality.

Nikon Coolpix S80 review

'S' means Style in the Nikon Coolpix range, and following on from the S70, the new Coolpix S80 brings improved features to the mid-range compact camera market with updated styling.
