I jail broke my phone and saved the 4.0 ssh blobs on tiny umberella...The phone started playing up so restored it, but itunes put 4.0.1 on the phone...I want to take this off as i think this is causing me to loose the internet connection on my wifi in the house...Have to keep putting it on manually...If i can go back how do i do it, this is the first iphone i ever had....Thanks Tony...
Got a tip for us?

As long as you are certain your 4.0 SHSH blobs are saved, then you can downgrade to 4.0 just fine. There are tutorials that will demonstrate how to do this. You need to edit your hosts file, so iTunes looks to Saurik's server to downgrade.
Anothther way to check is to look in Cydia. On the top of the Home-Cydia screen, in green writing, it should show what versions you have saved.
Since you didn't say what phone you have here's my TinyUmbrella tutorial:

Here's an overview showing how to downgrade with Cydia by editing hosts:

ok, will this work on ios 4.0.2. i had to restore my iphone and BOOM!! i am stuck with the latest firmware. i want 4.0 back. thanks.
Can't use jailbreak.me on 4.0.2
You need hashes to go back to 4.0 or 4.0.1 for 3G, 3GS and iPhone 4
If no hashes, you are stuck !
what hashes? i used redsn0w to jailbreak 4.0.2. and chose 4.0 but my version still says 4.0.2. im on iphone 3G.
A 3G now needs hashes for firmware 4.0 and 4.0.1
If you followed the directions for Redsn0w, then you are good for a 3G, Just point it at 4.0 (which you did).
4.0.2 for a 3G shouldn't be any problem.
