How do I get into my iPod touch without resetting it?

so i changed my password a couple days ago and after i did i locked my ipod. i got back on the next day and i realized i forgot my password so i tried various passwords and my ipod got disabled.. this has happened before and i had to reset my ipod on itunes..but this time i dont want to reset my ipod because i will loose all of my pictures and apps. how can i fix this? i would like to just restore it but i dont really knoe how to do it and i dont really know what it is..
