... "Hello" and then "Update Completed" and "there are just a few more steps to follow, and then you're done." Then it says to click on 'continue.' When I do that, the next step says "Apple ID Sign In" and "To finish setting up iCloud, enter the Apple ID Password" (for my email acct.). I'd never set up iCloud before this because my old operating system didn't offer iCloud. So I just installed Maverick on my Mac before updating to iOS 8 on the iPhone (which admittedly is an iPhone 4s but I don't think that should be a problem). After that, I hit 'next' and then it very quickly goes through this: 1. "Signing in" 2. White apple flashes on the screen quickly with black background I think... 3. "update completed" very quickly Then it goes right back to "Hello" and starts ALL OVER AGAIN. No variation on my part makes a difference, including skipping the option of setting up iCloud. Same result every time! In short, I can't get onto my phone. Can't make a phone call, can't check my messages, nothing - cause I can't get past this. I tried turning the phone off and then on again as well as my MacBook Pro (both with and without phone being plugged into laptop)...no difference on the iPhone. What do I do?! Thanks!!!
