The Apple iPhone 4 is the latest Smartphone by Apple available in the market. This phone comes with more improvised technical specifications than the older versions of this phone. First of all, taking into account the physical specifications, the iPhone is made up of panels of aluminosilicate glass which is chemically strengthened to make it more curable and resistant. The phone contains a high resolution screen with a 960×640 backlit LCD display. The IPS technology used by the Apple Engineers provides excellent color and contrast from almost any viewing angle.
The iPhone makes use of the A4 processor and with the help of this power efficient mobile processor, the iPhone can perform jobs like multitasking, video editing and making face time calls. Among more advanced features, this phone consists of a three-axis gyroscope and when paired with the accelerometer, various motion sensing operations such as user acceleration, angular velocity and rotation rate can be performed by the phone. The major difference between the iPhone 4 and the previous models is that the iPhone 4 has two cameras i.e. one front facing and one back facing. The front facing camera is designed especially for the sake of video calling.
According to Bloomberg, the sale of Apple iPhone may reach four million units in the United States to the end of 2011. According to the sources, this model has received positive feedbacks from the people for its improvised camera, voice recognition software and the faster processor.
