Have you dialed *228, option 1 to reprogram the phone to Verizon Wireless network?
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
i'm having the same problem today. i have tried to resync several times. grrrr....
i was hoping there would be some answers.
i guess it's time to try the apple.com support.
Im4Wine, you will need to connect your device to iTunes to restore Verizon Wireless service on your device. Once you connect to itunes using a USB, you will be provided with the option to restore your device. I hope this information is helpful to you. However, feel free to contact us for additional assistance. Keep us posted.^LH
Same thing happened to me while I was off network and roaming. Now I have no service even though I restored the iPhone4s. It had me call 800922-0204 which was too many voice connections without a real person. NOW WHAT do I DO!
