We look at what the latest iteration of Apple's iPhone operating system has to offer users.

Apple's iPhone OS 4.0 firmware update was probably the most anticipated update to the smartphone platform and it's easy to see why.

Previously, the iPhone was not a smartphone is the true sense of the word. Without multitasking and full Exchange services, the iPhone was a hugely advanced feature phone, but OS 4.0 has changed this.

Previously, iPhone firmware upgrades were mostly about bug fixing, adding only small, consumer-focused improvements such as copy and paste, improved Spotlight search, email search and MMS messaging.

Now the new OS has added a whole load of business-centric features to the mix.

Here's our guide to getting the most out of iPhone OS 4.0.
