How to get my music and pics to my iPhone?

I plug my IPhone into my computer and it shows up in my documents but it won't let me drag my music or pics over into it. How do I get it?

You drag on desktop then drag music and pics in

You need iTunes to put music or pictures in your iPhone or iPod. You plug your iDevice into iTunes, and you drag the music to the device. For pictures you have to sync a photo album from your computer or laptop

Why don't you try PC Suite for iPhone
