One of the most exciting announcements at Wednesday’s Apple WWDC was the anticipated arrival of the iOS4, the new operating system built for iPhone. The brand spanking new operating system comes equipped with approximately 100 new features, both new and upgraded. All of these delightful extras will be deployed on the iPhone 4G when it’s released throughout the world in selected countries on June 28^th.

However, don’t worry if you are still under contract for your existing iPhone. Current owners of the iPad, iPhone 3G/3GS and iTouch 2G/3G will be able to update their existing operating system to the new software.  During the keynote speech, Steve Jobs focused upon highlighting specific features contained within the iOS4. These included the ability to multitask, iBooks, file management and the all-new Apple advertising network ‘iAd’.  Unfortunately for Jobs, what with the dreaded Moscone Centre Wi-Fi fail, there just simply wasn’t enough time to go through every last detail and addition to the software. Some of the extra goodies will include the ability to gift apps to friends and support for wireless keyboards.

Two of the main feature upgrades are email and app organisation. iPhone iOS4 users will be able to neatly organize groups of similar applications into individual folders enabling swift and easy access. iOS4 enables iPhone users to handle a staggering 2160 applications on a single device. This feature will utilise the slick drag and drop functionality that owners of the iPhone have grown to know and love.

The new iPhone iOS4 will also see some significant alterations to the Email functionality. The iPhone 4G will enable users to manage multiple email accounts in one place, complete with threaded messaging and the ability to open attachments via third party applications.

Steve Jobs also announced some serious upgrades to the multimedia functionality of the iOS4 including ‘tap to focus’ video, the ability to create custom playlists using iTunes, 5 x digital camera zoom and a location based photo gallery feature called ‘faces and places’. This is not to mention the ability to customise background wallpaper, sending apps to your mates, a spell checker for mail/apps and support for Bluetooth enabled keyboards.
