How to restore iphone 4 after disabled?

I accidentally got locked out of my iPhone 4 and it says to connect to iTunes and i read the steps how to but i'm worried that it will not give me any of my data back, I'm only 13 and my parents won't be home till tomorrow and i have to be in touch with them and we don't have a home phone. I was also thinking about having my dad take me to the apple store tomorrow but i want to be able to call him tonight

Have you been backing up your phone to icloud or to itunes? If so, you first restore your phone to its original state then you restore it to a backup.

Don't panic - everything will be gone until you back it up.

When your parents get home let them know that you aren't responsible enough yet to be left home alone without a landline phone available. What if you needed to call 911? What if there was an emergency and you had to cal them? At 13 its not fair to you to be left with that much responsibility.

Hi disabled in this sense does not mean your phone or any other gadgets.
