Review of iPhone 4 - Performance

PERFORMANCE

Inside of the iPhone 4 contains a serious punch. It also had the same Apple A4 chip that is used in iPad having 1 GHz processing power. iPhone 4 had also 512 MB of RAM, which is a big step up from the 256 MB found in the previous model which is iPhone 3GS and it brings better performance when performing multitask.





Apple OS - iOS 4
They recently launched an Apple's latest smartphone with an OS iOS4 which is their latest Operating System and it brings a new features, including the greater support for multitasking as I mentioned above. iPhones have permanently been able to run Apple's own applications in the background, but this new version provides third-party software. Essentially applications are paused and only special service tasks will be running in the background. This new iOS 4.0 OS lets you store application icons in folders, provides you an enhanced inbox and lets you use Bluetooth keyboards.


Steve Jobs recently revealed the iOS 4.0 to the world and that was April 2010 and an expected launch in June 2010. After the announcement they immediately released to registered iPhone developers to begin testing their application.  



Wireless Features

The iPhone 4 has a typical quad-band HSUPA chip for data and voice, 802.11n Wi-Fi, and Bluetooth 2.1. There is a little modification in data-transfer speed in the iPhone 4 compared to the iPhone 3GS. This smartphone is experiencing signal issues when you hold it in your hands, especially in your left hand due to the iPhone's redesigned antenna. The conductivity of your palm is disturbing the two trim pieces where they meet and it results to signal drop. The signal returns to full strength until the phone is set down. A person that encountering this case isn’t having this issue, and it is generally doesn’t happen when you hold the phone in to your right hand, it happens only in left.
