Messed with the TIFF exploit, now have JUST an iPod web browser!

Someone help! well, i used the TIFF thing, and i used iPhuc and did the 3 power downs thing. Now, I have an iPod Touch that does NOT show any of my music or images… everything else works. Also, now there is a file in the directory of the ipod called com.apple.itunes.lock_sync I think this is some file itunes must’ve put in somehow. Plus, iTunes does not want to restore my ipod (error -18) Is there a way i can restore my ipod touch. This is my precious! I can still double click iphuc and i get access to my ipod , but i dont’ know my left from my right in this! I was too quick to play!
