My iPhone 6 is inoperable; I dropped my phone and the screen was severely damaged. I visited the Apple Store today and they said they could not replace the screen and offered to sell me a new phone. However, I need the data on my current iPhone backed up so it is not lost. The touch screen is not functioning properly. They advised me to backup my phone to iCloud via my iPad. My attempts have not been successful. In Settings, iCloud is tied to my husband's Apple ID, but iTunes is tied to my Apple ID. I cannot update iCloud's ID with mine - there is not an option to change it, his ID is greyed out. We believe iCloud was on due to the pop up notifications indicating the phone was not backed up to iCloud. I need help!! Can anyone navigate me through a process to successfully back-up my iPhone without use of the screen/touchpad?
