The new retina display is one of the improved features and claims to be the highest- resolution screen on a phone. The crystal-clear pictures are made out 326 pixels per inch, allowing the user to have a sharper and crispier image. Its enhanced technology switches applications without slowing down the performance of the app or draining the battery, and the quality of the camera has now 5-Megapixel, with built-in led flash, making even low light pictures look great.

As for the revolutionary technology, the new iPhone does not disappoint. To begin with, the new gadget has two cameras – the standard in the back, and now another one in the front. What is special about this dual-camera structure is that now, the user can switch from one to another during a video call. Both cameras can be used with FaceTime, a new feature that makes real video calls. With just one tap on the FaceTime button, users can video call friends from all around the globe, and show them what they see with the external camera, and have a face-to-face conversation through the internal camera.

Another innovative technology is the HD Video Recording and Editing. Now iPhone 4 users can edit their movies, and create their own masterpieces. The videos are recorded in a much higher quality, and for $4.99, users can edit them with the iMovie application, which makes the movie-editing experience much more sophisticated. With the application, videos can be enhanced with music and photos, as well as shared on the Internet.

Existing iPhone customers will not be able to get the $200.00 new-customer price from AT&T, and they will have to pay more to upgrade their iPhones. This is technology that keeps changing so much that, at some point, it re-invents itself. Like they say on the Apple website, “iPhone, the biggest thing to happen to iPhone, since iPhone.”
