Good News! I got my iPod touch back! It got stolen from my class last week. It was my friend who I let him borrow mine. Before this, I ask my another friend who is a witness and he wouldn't tell me the name of the thief. So I asked the security guard to tell him to spit out the word. Next day, I went to the office to see the security guard who I met him yesterday. She called another security guard to give me my iPod back. He brought the thief to the office. I didn't know it was my friend. The passcode in my iPod was change, I think he used *** mode to restore it. (The word is replace with three stars, don't worry) Yeah, Thanks for helping me.
