iOS 9 has a serious lag on my iphone 5, try running music app connect to your car tape thru usb lightningImproves what ?
Hmm...I had zero problems. Software downloaded and updated in less than 10 minutes.What the hell is wrong with Apple's CDN? I'm getting sub-megabit speeds downloading, both from the phone itself trying to do OTA and from developer.apple.com trying to get the IPSW.
I was noticing it taking eons to update the Starbucks app earlier too. It's been like this for a few days now.
