Parents upgraded their new iphone 6s to iOS 8.1. One phone now shows the plug into iTunes image. They don't have/nor access to a computer running the latest version of iTunes to fix the issue. I plan on driving over there this weekend with my imac to correct. In the meantime, can they pull the sim out of the 6 and drop it into their 4S that they still have and get a working cell phone until I can fix it.
