IPhone iPhone is synced?

The iPhone is synced with another iTunes library. Do you want to erase this iPhone with this iTunes library?

I got a new iPhone 4S, so I plugged it in my computer that I've used my iPod touch with, my computer is an old IBM ThinkPad that I've had forever. So I tried to drag all my songs in my iTunes library to my iPhone, but that didn't work. Then i tried syncing it, but that pop-up came out.

All the songs in the library are imported from the CD's I have, but what I'm asking is if I click Erase and sync, will it delete everything on my iPhone (apps, and pictures) or is it only for music purchased on iTunes?

It will delete everything in your iTunes library.

I've been listening to metal since 1980, Slayer since 1990, and playing guitar since 1987. You? Far from a troll, and one of the biggest metal fans you will encounter. Thank you very much. If you know anything about guitar you will know there isn't much thought put into Jeff's solos, especially his later stuff like Jihad which I mentioned. Thanks for once again making a fool of yourself Vincent.
