if one of the mods moves this to cydia support, you would be able to find more help most likely. I can't help your situation, never heard it before..is restoring an option for you?

Can I save all the downloads through cydia like ifile and Winterboard to my pc and add it to ipod after jailbreaking again? I got winscp. I have downloaded lot of stuff that will take long time to download again.

I think you could..I don't know, I don't anything about winscp besides how to establish a connection..sorry I can't be of more assistance!
