English to Chinese Tech/Engineering IT (Information Technology) Mobile operating systems

iOS 4.3 - Apple's home brewed iOS is slick and super fast. Since the previous versions have been really fast, ***there is not much you will notice in the new iOS 4.3***. The underlying potential of this operating system, can be seen only when you use high end applications that might challenge the way iOS 4.3 works.
iOS 4.3——苹果自行开发的iOS简洁优雅，运行速度飞快。由于前一个版本其实就很快，你在新的iOS 4.3中注意的亮点不多。
谢谢指正
