Apple has released the first update to iOS 7 since last September to the general public after a long beta test period. This update includes fixes for the TouchID fingerprint system, a fix for the home screen crashing issue, as well as the new feature for automobiles: CarPlay. Apple calls CarPlay “a better way to use iPhone while driving.” The system is only available on select new cars for 2014.
iPhone 4 users will enjoy improved responsiveness and performance with this iOS update.
