Hi! I cannot open up my device because I am locked out and need to connect to iTunes. My power button is broken and I cannot recover/ restart my iPod manually. I have had this iPod for 5 years and I have so many things I need to get off of it. I had lost it for a few months and the charger as well, and just recently found it again and would like to take the pictures of my daughter who had just recently passed. I tried to remember every passcode I have ever used on the iPod but none of them worked, and now I need your help! Also I have the 4th generation iPod.
