The legendary iPhone 4 has sold more than 1.7 million units in the first days of its official release in June 24th, 2010. New features are presented boosting its performance to the limits and setting new standards for the smartphone industry. Sleek design, a 5MP camera on the back and a secondary one on the front, Retina display, IPS technology for superb images at any viewing angle, gyroscope and Safari are only some of its killing features. But what makes the iPhone 4 a true technological marvel is its updated operating system, the iOS4. Now you can enjoy enhanced multimedia features such as multitasking, wallpapers, folders, FaceTime for video calls, the iMovie video editing app, Mail app, superior web browsing, iBooks and iAds.

In particular:

1. Multitasking

Apple cleverly realized that multitasking was missing from any of the previous iPhone versions. Now it is available for the iPhone 4 allowing you to fully operate different apps all at once without freezing or slowing down any of them. You can enjoy the latest 3D graphics games while listening to your favorite tunes straight from your Library or even Skype with friends while browsing your emails. Moreover, the new enhanced interface makes it easy to change between apps with a single tap.

2. Wallpapers

Jaibreaking has always been an issue for Apple. Many users choose to jailbreak their iPhones simply to change the standard iPhone wallpaper. Well, no need for that anymore and no fear voiding your warranty installing third-party apps as the iOS4 enables you to download and install the wallpaper you wish directly from iTunes. The list is massive and you can choose between free or paid ones to find the one that best suits your desires and mood.

3. Folders

Previous iPhone models allowed the installation of numerous apps. But, after a while, it became annoying to having to scroll and slide between apps to find the one you need. The new folders option is finally available making it easy to group your apps to categories. Apple has already preinstalled for you the ‘Games’ folder prompting you to follow their example with the rest of your apps.

4. FaceTime

Even though it is currently available only in WiFi, FaceTime has been characterized as one of the most popular video conference apps. The secondary VGA camera on the front is a great mean to share your thoughts and feelings without saying a single word. Additionally, with a single button you can change between the back and front camera sharing with your listener what you see without needing to turn your phone around.

5. iMovie

Finally Apple integrated High Definition video shooting in the brand new iPhone 4. The remarkable 5MP camera and the LED flash addition lets you shoot high quality video clips and photos even in night time. But, why stick with plain photos and video files? Download iMovie from iTunes, edit your video and photos, add music clips, themes, titles and create your own work of art! And if you want, share it with your contacts via email, MMS, YouTube or any social networking site you are using.

6. Mail App

As the official site suggests, ‘With Mail on iPhone 4, wherever you go, your email goes too’. No need to sign into multiple email accounts ; with the new Mail app you gave instant access to your Gmail, Yahoo, Hotmail, AOL and MobileMe inboxes in just a single page.

7. iBooks

Nowadays, ebook readers are the latest trend measuring thousands of registered users. Now Apple gives you the chance to read your favorite books and latest best-sellers straight from your iPhone 4! The enhanced iOS4 boosts the e-reading experience featuring bookmarks, highlight text onscreen button, notes and sync option to read your book from any other iDevice exactly from where you left it! Moreover, you do not have to convert PDF files to fit iPhone’s format as the iOS4 has now a preinstalled PDF reader.

8. iAds

Tired of getting thrown to the ad’s official page while you are playing? That is history in iPhone 4 as iAds enables you to explore the ad without needing to close your current app.

The iPhone 4 has been characterized as Apple’s best-seller. Brand new features, upgraded operating system, Retina display, faster web browsing, more than 200.000 apps to choose from, stylish design, FaceTime and much more make the iPhone 4 a must have.
