Apple iPhone 4 adds HD screen, video calling

Apple iPhone 4 shipping on June 24

Apple iPhone 4 includes HD screen

Apple’s next-generation iPhone has been revealed by the electronics giant at its developer conference in the US. The Apple iPhone 4 will launch on June 24 in the UK, and feature video conferencing and a high-definition screen that Apple claims is the highest-definition screen built into a phone.

The new iPhone 4 includes an upgraded 5 megapixel camera with LED flash, a new front-facing camera, the ability to record and edit video in high definition, a faster Apple-designed A4 processor, and a thinner, lighter design. Apple says that iPhone 4 will feature a longer-lasting battery with up to 40 per cent longer talk time, and the addition of a three-axis gyroscope for 3D control.

iPhone 4 FaceTime video calling

Apple gave video calling top billing. Called FaceTime, it will work with zero set-up between the new iPhone over wi-fi wireless networks. Apple says it is working with network providers to bring video calling over 3G wireless mobile broadband, but is promising to make video-calling ‘as easy as making a regular voice call,’ according to the company.

iPhone 4 has four-times the number of pixels of the iPhone 3GS with a 960-x-640 pixel display that Apple says has 78% the amount of pixels of its just-launched Apple iPad. Apple is calling its HD display ‘Retina’, and claims that at 326 pixels per inch, the human eye is unable to distinguish individual pixels on the touchscreen when held at normal viewing distance.

iPhone 4 Retina HD touchscreen

‘iPhone 4 is the biggest leap since the original iPhone,’ said Steve Jobs, Apple’s CEO. ‘FaceTime video calling sets a new standard for mobile communication, and our new Retina display is the highest resolution display ever in a phone, with text looking like it does on a fine printed page.’

The camera upgrade includes a higher 5-megapixel resolution, compared to the 3-megapixel resolution of the iPhone 3GS. It includes an LED flash that can remain lit when filming video, as well as new iMovie for iPhone software foe editing and sharing high-definition video on the iPhone. iMovie for iPhone includes transitions and themes, and can combine video, photos and music.

Apple iPhone 4 iBooks app

Apple said its iBooks ebook reading application would be coming to the iPhone, and the new phone will sport its iOS 4 – the new name for its latest iPhone operating system – that Apple claims has over 100 new features, including multitasking for running more than one application at once. iBooks for iPhone will be a free application, says Apple, and adds support for notes and viewing PDF format documents.

The iPhone 4 will have seven hours of talk time on 3G, and up to ten hours web browsing on wi-fi and six hours on 3G, according to Apple. The new iPhone will also have up to ten hours of video playback, and up to 40 hours of audio playback, Apple claims.

UK pricing is to be announced.
