Why has no one at Apple responded to this? It had been over 24 hours and you can't reply to their question? I have the exact same issue after the iOS9 update. I went to my local Apple store today and they had no idea, or any answers to the problem other then "We can restore it, but our restore could do damage to your phone" Well, I don't have the money for a new phone at the moment. This is a huge pain in the arse! Just for your information, it says that the upgrade was successful, cool! Before this I could slide my phone no problem, even after all the hard resets I can slide my phone, enter my pin and it comes to the updated successful screen, "just a few more steps to finish the upgrade". So it asks me to select my wifi preference, I do this and it asks me to slide the screen.... YEP, I can't friggin' slide it and I'm stuck on the white screen. We aren't all made of money and I had a perfectly good working phone this morning before the update and now I have a phone that is currently useless and you can't give us answers? Very poor!!!
