What's going to happen if I take in iphone and they see i don't have legal songs?

Okay, so my camera is broke on my iphone 4s, and i know that all of my contacts and stuff like that are backed up on icloud, however, i have 1, 181 songs on my phone and only 81 of them i have bought through itunes.So, if I take my phone in to get a new one, can they report me? And also, why can't I take the music on my phone and just put them in a new folder on my computer without syncing it to itunes. Because won't syncing it to itunes delete all of my un-bought songs?
Seriously in need for real answers and help!

Does a clean ESN matter with an unlocked iPhone?

I'm interested in an iphone 4s that I found on ebay. It says its unlocked but does not state if the ESN is clean or not. Since I'm using it under a net10 contract, would it matter if the ESN was bad? How can I tell if it is? I just really want to make sure before spending my money on a phone that I can't even use!
