Apple's iOS 8 may not look too different from the version that preceded it, but trust us: There are plenty of new bits and bobs to get familiar with once you start poking around. Now that you've had some time to dig into our full review, you can take iOS 8 for a spin yourself -- Apple has just pushed the update live, so check your iDevice's settings to see if it's your time to shine. Just keep a few things in mind before you enter the breach: The update will only install on the iPhone 4s and newer, the iPad 2 and newer and the fifth-generation iPod touch. Oh, and it looks like Apple is having some HealthKit trouble at the moment, so all HealthKit compatible apps have been temporarily removed from the App Store. According to tweets from Carrot Fit developer Brian Mueller, Apple has been saying that a fix is in the works, but there's no ETA on when it'll actually take effect. Nothing like a few hiccups to kick off a massive software launch, no?
