Apple has officially launched version 3.0 of the iPhone operating system.
The updated OS can be downloaded to any PC or Mac, and transferred to the iPhone via USB cable.
iPhone users can download the update for free, whilst iPod Touch users are charged $10 (£6).
The update adds over 100 new features an enhancements to the iPhone, including cut, copy, and paste functionality, a horizontal keyboard for applications other than the Safari web browser, and a Find My Phone service that enables users to find their iPhone if they lose it.
“Apple has really refined the experience they first delivered two years ago to the point where everything is head and shoulders above anything else out there,” said Michael Gartenberg, of market research firm Interpret.
Other new features include Spotlight Search – enabling users to search contacts, bookmarks, music, applications, notes, calendar, and email messages; and multimedia messaging – so iPhone users can finally send photos, audio files, and even Google Maps locations without having to write an email.
The new OS also allows for videos, films, and TV programmes to be downloaded direct to the iPhone and iPod Touch over Wi-Fi connections.
Previously, the iPhone only allowed users to download songs and podcasts direct to their device.
iPhone OS 3.0 will be pre-installed on the iPhone 3GS, whilst goes on sale tomorrow, and features an improved camera, a digital compass, and voice control.
