Apple acknowledges iOS 8.0.1 issues, posts downgrade guide, confirms iOS 8.0.2 in the works29
The Cupertinians' support page now says that iOS 8.0.2 is currently in the works and will fix the aforementioned issues. In the meantime, as a temporary work-around, the page gives users a step-by-step guide on how to downgrade to vanilla iOS 8 (yes, a guide to downgrading already existed, though it's good to see Apple come up with an official one).
It hasn't been a good couple of days for the new iPhones. First, there's the #bendgate fiasco, now – the iOS 8.0.1 blunder. Still, the devices have been selling out like hot cakes and it's doubtful that these hitches will put a serious bump on the road for Apple.
