Have you edited your hosts file to point to Cydia, this line :
74.208.10.249 gs.apple.com

yep

With the hosts file being edited, and you are getting error 3002.
Do this, download tiny Umbrella and check if you have shsh blogs with Cydia.

Edit : You have to click Advanced option to grab the required shsh blogs from Cydia, do the save shsh and display shsh, if you have any.
If you can't grab it, then you cannot downgrade.

i have done that too

It is very easy to find out if you have shsh blogs.
Download tiny Umbrella version 4.1.4
Plug your iphone into the pc, your iphone must be bootable.
Run tiny umbrella
click Advanced Option,
Highlight device/version, let's say iphone 4, 4.0.1 shsh
Request from Cydia
Then click Save shsh
Read what the answer say , it takes a minute or so
If it says restoring to the OS, will not succeed, you are too late.
Then don't waste your time, it just won't downgrade.
There will be a new jailbreak for 4.1 but now you can save 4.1 locally and push the 4.1 shsh to Cydia too eventhough you are not jailbroken.
