What I had seen is ,A rumor from a Chinese website claims that the iPhone 5 is delayed because the Apple’s dual-core A5 processor is overheating the iPhone 5. The cause may be from the bigger battery, and the smaller frame of the new iPhone. This same processor is currently found in the iPad 2 although it does not have an overheating issue in the iPad 2. Due to this issue, some believe that the next generation iPhone will not be launching, but Apple will launch a minor upgrade version of the iPhone 4 which may be named iPhone 4S. The launch of the new iPhone is expected later this year and whether it will be called iPhone 4S or iPhone 5 is still not for certain. Do share your opinions!!
