If you get this error when trying to upgrade the operating system on an iPhone or iPad:
"There are purchased items on the iPhone (iPad) "[name of device]" that have not been transferred"
Things to try:
- Is your computer is already authorized to the iTunes store account being used on the device? If not, authorize it:
Open iTunes. From the Store menu, choose Authorize Computer. In the dialog that appears, the Apple ID button is selected by default. If you have an AOL account, select AOL. Enter your Apple ID or AOL screen name and password, then click the Authorize button. If the iTunes Store purchases on your device were purchased with multiple accounts, you will need to authorize the computer for each one.
- Try manually transferring purchases:
With the device connected to the computer, select its icon in the left column of iTunes, and select "Transfer Purchases from "Your device name" from the File menu.
- Try unplugging the device, deauthorize and then authorize the computer, plug the device back in and try updating again.
