Hardware and Styling

It is also home to a 5 megapixel camera with LED Flash. The phone itself is like an expensive piece of jewellery. The gorgeous 'Retina Display' and the home button dominate the front.  The sides are tapered with a steel band, which also doubles as the dreaded antenna, which caused the infamous iPhone death grip issue which was causing call drop outs in the US.

On the right side is the micro-sim port while on the left Apple has provided the redesigned volume buttons (previously a volume rocker) and the mute button. The top of the device is home to the 3.5mm port and the power button while the bottom houses the 30 -pin connector slot.

Interface

The iPhone is home to the simplest smartphone OS in the industry, the iOS. So simple to use is the iOS that this reviewer's eighty-year-old grandfather dumped his laptop for the iPad, which also uses the iOS.

The home screen of the iOS provides a wall full of all the applications installed on the device. There is also a Mac OSX like dock which allows four apps to be opened simultaneously and which can be customized by each user. Just swipe towards the right to reveal the other apps. Unlike other operating systems there is no menu button to reveal all the apps, the apps are just there.

This user interface works since it has no learning curve, making the iPhone a plug and play device for novices.
 

There are no widgets in iOS. This is a disadvantage as one has to no way of viewing information without entering an app - cue the Weather and Stock apps. On Android, widgets act as shortcuts and provide considerable information. Similarly, the tile interface on Windows Phone provides similar access to information.

iOS, in its current form, has a fairly bad notifications system which is very intrusive in nature. For example, with news app open in the background while playing Angry Birds, the app will flash the notification right in the middle of the screen pausing the gameplay. This happens even if the user does not want to view the notification. Fortunately, iOS 5 - which was shown off at Apple's World Wide Developers Conference in June - will have a revamped Android like notifications system along with other goodies.

The onboard keyboard is the best virtual keyboard on the market. Keys are well spaced and OS provides brilliant auto correction abilities.

Multimedia

The iPhone is the home to the world's best MP3 player, the iPod. There is simply no arguing with this statement. It is definitely a multimedia leviathan.

Like all iOS devices, this contains a movie player too. But, the biggest disadvantage of this app is its lack of support for popular video formats. One has to go through a lengthy conversion process for videos.

The 3.4-inch display boasts of a 960x640 resolution, which is currently the highest among all smartphones. It even has an astounding pixel count of 326 PPI through which it gets its Retina moniker.

Apple has upgraded the camera of the iPhone with a 5-megapixel OmniVision sensor. The images are very vibrant and the color reproduction is very impressive.

As far as 720p video recordings go, the iPhone is right on par with the Sony Ericsson Xperia Arc and the Nokia N8.

Another feature, which makes the iPhone a multimedia monster, is its 16GB and 32GB memory capacities. 16 GB should be enough for most but media gobblers would appreciate the 32GB capacity. Unfortunately, we don't get a memory card slot for expansion.

Performance

At launch, the iPhone 4 knocked the wind out of the competition with its blistering performance. This was possible because of the A4 processor, which is clocked at 1GHz and a meaty 512MB of RAM. We are told that Apple has under-clocked the A4 processor to 800 MHz, but it still scorches. Even today, in comparison to dual-core NVidia Tegra powered smartphones, the iPhone 4 feels like a screamer.

This is inherently because Apple develops its own software and hardware. The software is always in tune with the hardware, which helps Apple derive more performance from lesser hardware. The same cannot be said about the modern Android Smartphones, as all Android phones don't have a standardized hardware spec.

The call quality of the Airtel iPhone can be best described as average. We haven't really faced the now legendary 'death grip' issues but its still not the best calling experience. This could be a combination of factors involving the network and the Phone.

The iPhone surprised us with an impressive battery life which lasted a day, which include constant 3G or Wi-Fi, Web browsing and phone calls while playing multiple games. It was very impressive and easily bested the Android competition. 

Price:

Price tag starting at Rs 34,500 for the 16Gb version and a ridiculous Rs 40,500 for the 32 GB.
