Help! updated to 3.1, got error, won´t restore!

[Seppola]

I updated my iphone just a few minutes ago, and i got an error midway. I thought I could just restore and then do it again, but it won´t restore.
I tried to update on another computer, not the one I´m synced with.
When it happened I was clicking trough the menus, but everything showed gray, so I didn´t click anything.
I connected it to the computer it´s synced with, and I get an error there too.
I only get up unknown errors, last one was "(13)".
My brother did this a few minutes before me, and it went fine.
What can I do?
