More Customization for iOS 9
We are starting to hear about new iOS 9 release prep from Apple, but there is still a lot left to learn. Apple focused on a major update to the iPhone and iPad software with iOS 7 in 2013. This changed the overall look of the user interface, but did not allow for more customization like a jailbreak does.
It would be great to see Apple finally allow users to customize the iPhone interface with more than just a lock screen and a home screen image. HTC does this without breaking any user interface details thanks to an option that lets the user choose what color to use for the bulk of the interface while the rest remains the same.
