If you don’t trust iTunes backup, you should use SCP or iPhoneBrowser and copy /var/mobile/Library/AddressBook to your computer. This contains your contacts. While you’re at it you may want to copy all these:

/var/mobile/Library/Calendar – Your calendar
/var/mobile/Library/Notes – your notes database
/var/mobile/Library/Safari – your bookmarks and cookies
/var/mobile/Library/SMS – your text messages.
