Error 1403 for firmware 2.2

[saifeeab]

For the past two days I have been trying in vain to update my iphone firmware to 2.2. Everytime i use restore in iTunes i get an error message "An unknown error occurred (1403)". I have tried to download the firmware from different sites thinking one might be corrupt. But so far I still get the same msg . I used restore as well as update keys but both give the same.

Please help guys !!

PS.: I have upgraded my iTunes to 8.02.

I just answered your other post....Put the phone in DFU mode.
