My iPod Touch (or iPhone) gets backed up by iTunes every time I sync it. Now, I would like to restore it from my last backup to get some of my data back. How do I do this?
One trick is to reset your iPod Touch/iPhone.
On the home screen, open the Settings application. Press on the General item. Scroll to the bottom of that screen and press on Reset.
You will then have the option to “Erase All Content and Settings“.
Then, the next time you plug your iPod Touch or iPhone in the computer, iTunes will ask you if you want to restore it or start anew.
