i tried to downgrade but just not working ....

This is why I say that you do not seem to know what U are doing. If you can elaborate a little more what you are trying to do or did ( step by step ) you may get some help. If you just say "I tried to downgrade............." what can U expect others to tell you ??

So I understand you are a legit AT&T user, you shouldn't have problems activating using your AT&T SIM in iTunes.

ok here is the step by step things i did.

First of all ... i bought my iphone in the states and never used it there as i am from the UK. I did a jailbreak and unlocked it and was using my O2 pay as you go sim. Recently my phone froze and i restored and updated it to 2.0. Now it says invalid sim. when i insert my AT&T sim it asks me to activate. Which i haven't done. I want to jailbreak and unlock the phone so i can go back to using it with my O2 sim.

Now to downgrading.
1. I uninstalled itunes 7.7
2. reboot and renamed my itunes folder to something else.
3. installed 7.5
4. downloaded 1.1.4
5. put my phone is recovery mode/ dfu mode....
6. clicked shift and restore and selected the 1.1.4 i downloaded.
7. after a while it comes back with an error.....the iphone cannot be restored. an unknown erroe occured (20)

bruv .. i have a o2 pay and go ... why would i need to get another ?

Do you really wish to downgrade? Wouldn't you prefer to use the iPhone 2.0 software instead?
I would suggest you restore using Apple's 2.0 (upgrade to iTunes 7.7 and just click restore) then use winpwn to do everything else.

EDIT: replaced PwnageTool with winpwn, forgot you are on Vista
