Yes, it didn't work. I brought it in to the Apple store yesterday evening and they tried everything to no avail. They recommended I purchase a replacement phone or call my phone insurance company. I went back to the Verizon store explained everything, called Asurion and payed for a replacement phone. Still wondering why my phone stopped working after an update...
