I want to back up my iPhone
I have a new computer. I have stated that I trust this device, on both the computer and my iphone. I loaded itunes and made sure that both my phone and itunes are running the latest versions. I have tried turning off both computer and phone for an extended period. My device is recognized by the correct name when I connect it to computer and itunes. However, when I click on the device icon and wish to back up my iphone the button to do so remains grey and I cannot start the back up. What else can I try? Perhaps a different cord to the computer? Although it did recognize my device properly in itunes. Please help. I would like to get my phone backed up asap.
