The iPhone 4 is the new device launched by Apple which may or may not please you with its new avatar
. You will find some similarities between the iPhone 4 and its previous versions, iPhone 3G and 3GS. However the latest version gives you an entirely different feel and looks much better. The physical dimensions of the iPhone 4 are similar to the 3GS model but the newer version is much slimmer. Overall the it looks better than its older versions but you may find it less comfortable to hold due to its poor grip.
The phone features a large 3.5 inch capacitive touch screen which is simply awesome. It has a resolution of 640 X 960 and supports 16 million colors. The screen is marketed by the name Retina by Apple and is the best display that one may find in the GSM phones. The Retina produces vibrant colors and high quality images and also has superb sunlight legibility.
The still camera has a 5MP sensor and also features AutoFocus and Touch AutoFocus. The Touch autofocus feature allows the user to track moving objects and the AutoFocus feature focuses objects placed at different distances. Talking about the video camera, one can produce High Definition videos with resolution of 720 p and at a frame rate of 30 per second.
The iPhone 4 uses the iOS 4.0 which works perfectly and delivers its full potential through this device. iOS 4.0 can also be installed in the previous version of the iPhone family i.e. iPhone 3GS, but it will make it slower and degrade its performance. The reason behind better performance of iOS 4.0 in iPhone version 4 is its better hardware hard ware configuration that includes a better screen, improved still camera and camcorder and gyro sensor.
The iPhone 4 has a tiny gyroscope inside for helping with six axis motion detection with preciseness. However the problem of low signal is still continued in this version. However, apple has brought out these new accessories called 'bumpers' to battle the problem of signal and thus cover its only serious flaw. This is overall a fantastic phone and well worth buying.
