iPhone 4 stuck on plug into iTunes screen after updating.
I updated my iPhone 4 today. I click on the install update under settings and the plug into iTunes screen appeared. I plugged in my iPhone and let it update. When it was finished, the plug into iTunes screen stayed, so I tried to restore it. An error message appeared iTunes and said my iPhone was unable to restore. I just bought it yesterday. I also tried holding down the home button and wake button and it didn't help. Please help me!
