After pushing out several betas, Apple's finally ready to roll out its latest firmware update to the masses. iOS 7.1 is now available as a free download, and as expected, it adds a few new features to the mix. The new update should be heading your direction if you own an iPhone 4 or newer, iPad 2 or newer, either iPad mini or a fifth-generation iPod touch. Among the usual smattering of tweaks to the iOS UI and bug fixes, the most notable feature improvement is the inclusion of CarPlay support and fixes for the random reboot problem many iOS 7 users have been experiencing.
