Apple revealed updated versions of the iPod nano and iPod touch at the company's press event for the new iPhone 4s yesterday.

iPod nano

Apple has made the iPod nano's multitouch display easier to navigate by using larger icons. Phil Schiller, Apple's senior vice president of worldwide product marketing who unveiled the new products at the company's Cupertino headquarters, also said that Apple has improved the experience of using the nano for fitness. "Right out of the box, you can go on a walk or a run as well, without adding sensors or devices," he said.

Schiller also mentioned that companies have create watchband cases for the nano so people can wear them on their wrists, and that the latest nano features 16 new clock faces for those people.

The new nano is also a little less expensive than before. The 8GB model costs $129 (£83) - down from $149 (£96) - and the 16GB models costs $149 (£96) - down from $179 (£116) . Both sizes are available now, and come in seven colors.

iPod touch

Apple also updated the iPod touch on Tuesday, introducing a white model for the first time (see top image), and dropping the price for the low-end model.

The iPod touch costs $199 (£129) for the 8GB model - down from $229 (£148), $299 (£193) for the 32GB model, and $399 (£257) for the 64GB model. They will be available, alongside iOS 5, on October 12.

Schiller said that the iPod touch is Apple's most popular iPod. Earlier in the presentation, Apple said that it has sold more than 300 million iPods to date.
