Question : Problem: How copy mp3 to iPhone without iTunes?

Here's the situation...

I'm on a road trip.  My PC at home has iTunes on it and it's what I usually sync my iPhone with.

My laptop does not have iTunes on it.  Few questions...

1.  If I install iTunes on my laptop and sync my iPhone will it copy the MP3's from my iPhone to my laptop?  Or will the iPhone be purged of all the MP3's because the laptop has nothing?
2.  I downloaded a MP3 from a website (legit MP3) and want to copy it to my iPhone.  Any way to do this easily without having to download/install iTunes onto my laptop?

Thanks!

Ok, here goes:

1:  If you install iTunes on your laptop, and sync, the iPhone will be cleared of all music and will try to sync the music that the laptop has to it.

Due to Apple trying to keep record companies happy, you can't go grabbing tracks off the iPhone and into iTunes.
*You might find other software that will do that, but iTunes will not*

2:  Reportedly, you can use other methods to copy songs to your iPhone, such as:
