iPhone 4
When creating iPhone 4, Apple designers and engineers didn’t start with a clean sheet of paper. They started with three years of experience designing and building the phones that redefined what a phone can do. iPhone 4 is the result of everything they’ve learned so far. And it’s all contained in a beautiful enclosure a mere 9.3 millimeters thin, making iPhone 4 the world’s thinnest smartphone.
All the breakthrough technology in iPhone 4 is situated between two glossy panels of aluminosilicate glass — the same type of glass used in the windshields of helicopters and high-speed trains. Chemically strengthened to be 20 times stiffer and 30 times harder than plastic, the glass is ultradurable and more scratch resistant than ever. It’s also recyclable. More over it comes with iOS4
iOS 4
As most know not long ago Apple released a new version of the operating system through which run the iPhone, that you knew before the upgrade to iPhone OS and later renamed iOS 4 . However, server, like many thousands more, when Apple officially launched iOS 4 via iTunes, updated its iPhone 3G to this version of operating system and surprise, the terminal became very nearly useless brick: slow to when opening applications (a lot), hang in various apps (Seesmic or the application of maps for example) and extreme hardship to the time of writing (this is what happened to me, other users report different errors, such as inability to use 3G).
