We recently upgraded our LGENV2 phones to iPhones (one iPhone 5, two iPhone 4ss, and one iPhone 4). Three of us transferred our contacts to our phones at the Verizon store. One of us used Backup Assistant to backup the contacts, then downloaded them to his phone. When he did this, the contacts downloaded to all four phones. For some reason, we all have each other's contacts now. When one of us updates or deletes a contact, it does the same action on all four phones. The rep at the Verizon Store thinks it's because we all use the same iTunes ID. We want to keep the same iTunes ID, because when one person buys a song, TV show, or movie, then we all get it. Hopefully there's a way to keep contact updates from taking place across all the phones. Appreciate any help you can provide in fixing this. Thanks!
