Apple has announced that it will be adding five new applications to the iPod touch, including Stocks, Mail, Notes, Maps and Weather as found on the Apple iPhone.

However rather than offering it for free as is normally the case, the company has said it will be charging customers of the iPod touch $20, or £13 in the UK, to upgrade the software.

The news is likely to annoy customers, as the same software is available to Apple iPhone customers for free.

The move means however that Apple iPod touch users will be able to get Stocks, Mail, Notes, Maps and Weather information using the wireless connectivity of the device.

The software update will be available from today.
