Where Do You Illegally Buy A Platypus If I Buy The IPhone G3, Can I Download Songs Illegally And Transfer Them To My IPhone 3G?

If I buy the iPhone G3, can I download songs illegally and transfer them to my iPhone 3G? - where do you illegally buy a platypus

I use Limewire and downloading songs illegally. I wondered whether I could transfer my songs illegally downloaded on my iPhone 3G. If so, do I buy an accessory to do? Where can I connect to my computer and transfer songs to my iPhone 3G?
