Why does Itunes want me to restore my ipod touch
Today my iPod asked me to update from ios 5 to ios 6. I decied that I had time so I agreed. While My iPod was updating I plugged it into my dock to charge. When it was charged the update was complete so I turned it on. It came up with a picture notice saying plug into iTunes 
like above. So I plugged it into iTunes and it said that I had to 'RESTORE MY IPOD'. But I have a few paid for apps and important photo's on my iPod and I don't want to have to pay for them again/lose them. Please help me as my iPod is very important and I don't want to have everything restored to factory settings.
iPod touch, iOS 6, 8gb
