Expert advice requested! how do I downgrade to 1.1.1

Please see my previous posting,
So is Itunes 7.5 the problem,

I don't seem to be able to downgrade my phone back to its 1.1.1

Thank you in advance,
Viperdad
 
Be veeeery careful, I used Jailbreak.jar after quitting iTunes, it rebooted and now I'm stuck at 'SIM Locked' no way to get anyfurther....
EDIT : Found out how, delete iTunes 7.5, install old version of iTunes (7.4.2), re-install firmware 1.1.2, delete iTunes 7.4.x, re-install iTunes 7.5, re-activate iPhone. Phew...

Did this return you to 1.1.1 ?
