The iPhone 4 provides HD video recording with its 5 megapixel camera along with a front facing VGA camera for the FaceTime app which allows you to easily make video calls to friends also on iPhone 4. The handset also has the latest operating system iOS 4 which allows you to create Folders for apps and multitask.
The handset features a 5 megapixel camera with tap to focus capability along with an LED flash for light enhancement in poor conditions. Your photos and videos are also automatically Geotagged allowing you to create albums based on location as well as date, as with the HTC Desire HD. The phone also features a large 3.5 inch Retina display which makes everything on the multitouch screen extremely vivid to view, including all of your videos in High Definition and photos captured. The display has a 960 by 640 pixel resolution at 326 pixels per inch respectively, making it the highest resolution display of any phone currently released.
The iPhone allows you to use multiple applications at any time and switch between them seamlessly leaving one to go to another without losing your place. For example you can change the album you are listening to in the iPod app, and go back to the email you were composing instantly. This is similar to the Desire HD which also allows you to multitask. As well as the new multitasking functionality, the iOS 4 operating system also now provides Folders which allows you to organise your apps into easy to manage places with custom names, or with automatic names based on genre. This means that you can add even more new apps to your handset from the preinstalled iTunes App Store. Otherwise, the common interface on the Home Screen remains the same with a simple layout of App icons for you to tap to open.
The iPhone 4 also provides great calling features too, along with the new FaceTime app for video calling friends using the front facing VGA camera on the newly designed handset, which now features a more robust casing and display glass cover. It is similar to the Desire HD in many of its features including video calling and multitasking too. Meanwhile, it also offers easy email and messaging features as well as a full iPod and the means to download and add more and more music to the phone all the time, and apps from the App Store also.
