I upgraded to 1.1.2 (prepped with OktoPrep).. Jail breaking isnt working.. So I need to restore my phone back to 1.1.1

However, my computer doesnt have an updated version of my contacts.. and I can't back it up because I am stuck at the iTunes activation screen..

Any ideas on how I can backup the phone before I restore it?

I can use iBrickr to go down to 1.0.2 but does it RESTORE it to 1.0.2 or DOWNGRADE it 1.0.2 (meaning I wont lose my stuff).

Any help is MUCH appreciated!
