A host of new and updated applications are expected to launch to support the iPhone 4, which now has new multi-tasking functionality.

One of the first companies to announce it will be updating its application for iPhone is satellite navigation software producers TomTom.

The new updated TomTom iPhone software will enable you to run your navigation software while you also undertake other tasks on your mobile.

The good news for those who already own the software is that you will be able to upgrade to the new version for free.

TomTom have also taken this opportunity to offer discounted prices with the UK and Ireland version now costing £54.99 and the Western European version just £42.99. They’ve also announced a new price for HD traffic updates which now cost £22.99 a year.

You can download TomTom for the iPhone from the Apple store.
