Apple iPhone 4 Review
Apple’s new iPhone 4 features a completely new design over previous iPhones with the new 3.5inch multi touch screen retina display on the front, which features toughened glass. The stainless steel band which covers the sides is where the various antennas are housed, while the sleeker design is without any ridges for dirt and dust to collect in. The solid build of the iPhone 4 means there is no creaking or rattling when the phone is mishandled.
The iPhone 4 features a 3.5 inch multi touch widescreen display with a 960×640 resolution at 326 pixels per inch. The 1GHz processor and 512MB of RAM provide a super fast and glitch free system with a choice of either 16GB or a 32GB storage, plus integrated 802.11 b/g/n WiFi, Bluetooth 2.1+EDR, A-GPS and a digital compass. The battery life of the iPhone 4 is impressive in comparison to previous iPhones with around 36 hours of battery life with normal to heavy use.
The iPhone 4 features raised volume buttons and mute switch on the left side of the phone which offer good tactile feedback for handling during calls.
The SIM card slot is located on the right side of the phone, and the iPhone 4 makes use of a micro SIM card. The wake/sleep/on/off button and headphone jack are located along the top edge of the phone as well as the second microphone, while the bottom edge of the phone features the main microphone, dock connector and speaker. The 5 mega-pixel VGA camera is located on the back of the phone with the new LED flash next to it, and the additional 5 mega-pixel front facing camera is located on front of the phone making it ideal for the built in FaceTime application as well as portrait photographs.
The video capture of the iPhone 4 records at 720p although the iPhone will compress the video to 568 x 320 resolution when emailed or uploaded. The uncompressed video can be transferred to a computer using iPhoto or applications such as Pixelpipe.
The retina display on the iPhone 4 offers users high screen sensitivity which makes it easy to scroll, pinch and zoom using your fingers on the screen as well as an unmatched crystal clear picture.
Performance on the iPhone 4 is what users have come to expect from iPhone and more. The iOS4 software features on the iPhone4 include folders and multitasking to increase usability and simplify tasks. The folders function allows users to organise apps into folders by dragging it on top of another icon to create a new folder. Multitasking allows users to switch between apps by double pressing the Home button. This will display recently opened apps at the bottom.
An additional feature included in the new OS4 is the handling of emails on the iPhone 4. The new unified inbox allows users to manage all email accounts in one unified system to be able to see messages from all accounts in a unified inbox and organise these messages by threads and open attachments in third-party apps. The new iBooks feature is an e-book reader and bookstore application which allows users to view and purchase e-books on their iPhone 4.
Overall, the iPhone 4 seems to address the issues experienced with previous iPhones successfully. The new design and operating system provide a smart phone that is easy to use as well as offering the wide range of apps that iPhone users have become accustomed to.
