"Your Firewire GUID couldn’t be recognized and therefore music importing will not be available.
To solve this issue, you will need to do some hacking.
To learn how to connect to your iPhone and or iPod touch see this post.
Log in to your iPhone or iPod touch with SSH and do the following:
1) check if you have “ioreg” binary in /usr/bin/ directory
2) If not download it from here and upload it to /usr/bin
3) chmod 755 /usr/bin/ioreg
4) run chown mobile:mobile /Applications/iSlsk.app/
5) run chown mobile:mobile /Applications/iSlsk.app/*
6) Download libncurses.5.dylib from here and upload only libncurses.5.dylib to /usr/lib
7) run chmod 777 /usr/lib/lib*
IF you still can’t get it to work i suggest waiting for the next release.
Thanks to the original creator Errrick who’s website you can consult here."
