Please can someone tell me how to restore my iPhone.
I tried to upgrade to 2.01 from 1.1.4 and now my phone wont work at all.

I have tried to restore through itunes (shift and 1.1.4ipsw and 1.1.3, 1.1.2 etc. But all i get is errors).

How can I totally wipe my iphone clean and start from the beginning again?
