I know some other people have had this problem, but their solutions didn't work for me, so I thought I'd throw the question back out. I chatted with a Verizon customer service person yesterday and he said something about the update from Apple's end makes it so the Verizon network can't authenticate my phone. I've done several full factory resets, my wifi works fine, but I get no service and when I plug into ITunes it doesn't even recognize my phone number. The Verizon person I talked to said he'd send the bug to their engineers and it would be fixed in a few hours, but it's been a day and a half and nothing has improved. Thanks in advance for any help!
