Hey. Ok so I turned my ipod on last night for it to tell me to plug it into the pc so it could connect with itunes. It was fully charged and I don't have a passcode for it. Why did it do this? It works fine after I did so - but I'm going away to America for a month with no computer. What if it does it again? I need my ipod for emailing my family. Please tell me how I can prevent this happening and why it happened! Thanks in advance.
