Mobile-Review Editor-in-Chief Eldar Murtazin posted on his Twitter handle that Apple will drop support for the iPhone 3GS in iOS 5.x due possibly due to hardware incompatibility. The source of Murtazin's statement is still unknown. However, iOS 5 is supposed to be a major update it makes sense for Apple to try and avoid the same problems it had with the iPhone 3G on iOS 4.x. It make it clear that iOS 5 would a launch alongside a new device since Apple would be left with only one device on its latest firmware release.




This means Apple’s A4 chip will be a minimum threshold requirement for running iOS 5 which will be unveiled at WWDC this June. So, it’s best for you to stick to iOS 4.x on your iPhone 3GS if you want to keep it running like a breeze.
