As we know, when apple just released iPad 2, iPad2 can’t smoothly playback 1080p video . And even iTunes does not recognize video files higher than the 720p. Now it appears that this is entirely Apple’s software restrictions. For further testing about the latest iOS 5, we found that not only iPad2 on iOS 5 get the capability of 1080p playback, even the iPhone4 and first-generation iPad with previous A4 processors can get flawlessly playback of 1080p video.
To be more amazing, the developers have found that Apple has provided an open API in iOS 5. This will support 1080p video output,processing and provide real-time video capture and playback during video clips. This means the fifth-generation iPhone will sport 8 megapixel camera to support 1080p video shooting.
Currently there are four Devices of Apple which support 1080p video playback smoothly: iPhone 4, iPod Touch4, iPad and iPad 2. Thus the long-term speculation has been confirmed that Apple intentionally add the software limits to the performance of iOS devices to make some room for the future’s upgrades. But for iPhone4 users who owns more than a year, isn’t it a bit cruel without capability of 1080p playback?
