Update: iOS 8.1 launches on Monday. Here's an explainer of all iOS 8 features before you download it
Compatibility
When it comes to iOS 8.1 and iOS 8 compatibility, Apple requires an iPhone 4S or newer and iPad 2 or newer to update to the latest software. Only the iPhone 4 is cut from the list.
Both the iPads mini and iPad mini 2 tablets and the forever alone iPod touch 5th generation are also going to work with the new iOS, just like they did with iOS 7. No one besides 2010's iPhone 4 gets left behind.
iOS 8 updates and problems
While we wait for the iOS 8.1, the latest version of iOS 8 is the safe-to-download iOS 8.0.2 update. It fixes a bug so Healthkit apps can populate the App Store and tie into Apple's Health app. Third-party keyboards should be glitch-free too.Release notes for this patch mirror the ones found in iOS 8.0.1, which Apple released one a week after iOS 8 launched. It was quickly pulled as it introduced problems like breaking Touch ID and cellular.
iOS 8 camera time-lapse mode
Believe it or not, the iPhone is consistently the most used camera in the world. It's in so many hands and so easy to use. In iOS 8, the camera app is going to get even better.iOS 8 and OS X Yosemite are going to be joined at the hip with the Handoff feature that lets you pick up where you left off between devices.
OS 8 extensions
Extensions open up iOS 8 to Android's best input methods: Swype is here and SwiftKey breaks free of its SwiftKey Note standalone app confines. Fleksy and Minuum also give you control over keyboard sizes.
