The launch of iOS 9 was supposed to be a joyous occasion if you own an iPad, iPhone or iPod touch, but it didn't always work out that way. A bug left some stuck on the "slide to upgrade" screen, preventing them from using their gear unless they rolled back to iOS 8 or started fresh. If you're one of those glitch victims, you'll be glad to hear that relief is in sight: Apple has released an iOS 9.0.1 update that (you guessed it) makes sure you get past that upgrade screen. It also tackles a few other hiccups that could sour your initial experience, including one that prevented some alarms and timers from playing. As such, you'll probably want to check for the update right away. And if it's too late to avoid the worst, Apple's support site (linked above) has a guide to getting your device back to normal.
