Sync new songs to iphone without deleting all the old ones?

I have over 500 songs on my iPhone 4, and most of them were from ripping my dad's CD's.

I do not live at my parents' house anymore, so I no longer have access to these CD's.

My PC's hard drive recently died, leaving me with no music whatsoever. (Yes, I sort of had it all backed up. See it kind of WAS the backup. It had all my music, pictures, games, etc. On it that normally are also on my C:\ drive. Problem is, the backup drive died the night I reformatted and re-installed Windows 7.)

Now the only copies of All of my music are on my iPhone, and iTunes INSISTS on deleting all of it before letting me add anything new to it.

Is there anyway whatsoever I can take all of the music off of the phone first? Or ignore itunes' bull$#! 7? Also, of secondary concern but if at all possible, contacts, photos, notes, etc.

Oh, it is jailbroken.
