Hi, I have been on this website and found a lot of things that I have already done on my phone but I have a few questions that I need help with:

1) Where is the "Windows directory located? How do I get to it? I know is an important folder because many apps save files on it.
2) Another thing I have been trying to do is chage the sliding sounds. I know that there is information on these boards about it but I can't understand what they want me to do.
3) I also would like info on how to make my media player look like an iPod.

I know is a lot to ask for but I am a noob and need it explained in terms that someone like me can understand.
