The iPhone4 delivers on all fronts

The iPhone 4 has arrived, and with over 100 new features to work with, it promises users a unique mobile experience. The stainless steel casing and all-glass front beautifully encompass a device that is 25 per cent thinner than the iPhone 3GS. If there's a sleeker and more appealing model in the world of mobiles, we haven't met her yet!

In a radical departure from previous iPhones, the wise heads at Apple have decided to place the volume controls on the side of the phone with an accessible microSIM tray. Two of the features that you might rank among your favourites on the iPhone, the camera and the microphone, are located on the front and the back of the phone, respectively.

There are so many fantastic new features with the iPhone 4, it'd be impossible to enlighten you about them all here, but a there's a few you might be interested in hearing about.

The 3.5 inch screen boasts a resolution of a whopping 960x640 pixels, which is, in fact, higher than the human eye is capable of perceiving. But that won't deter developers producing some incredible apps for this beast of a screen.

And the ultra-powerful A4 chip has revolutionised power management. It gives you up to 10 hours of WiFi browsing, 40 hours of music and a standby time of around 300 hours. Phenomenal.
