Download the firmware from here

Save it to your desktop.

In itunes, hold shift key and click restore. You can then choose which firmware to use (i.e the one you saved to your desktop).
No its not possible because apple do not sign the 4.01 firmware anymore due to the pdf jailbreak,
I tried downloading but no joy
Sorry unless you have SHSH blobs saved from a previous jailbreak then you just have to wait for the iphonedevteam to jailbreak the 4.02!
I think the blobs are saved how can I upgrade?? To 4.01
Cheers for that I Wil check later.
