I have mistakingly restored my previously jailbreaked and unlocked Iphone 3gs on Itunes so now is locked. Have tried jailbreaking and rebooting with redsn0w but can´t get pass the activation screen on the phone. It says I need to insert a valid a Sim card with no pin lock to activate the phone (won´t read mine) I´ve even tried jailbreaking using 5.1 ipsw and boot tethering and will get to the same point. Also tried jailbreaking with Install Cydia unticked. The custom software is 06.15.00 I cannot access to any other information now since the phone won´t go further than the activation screens Could you please please help me? I will need as detailed steps as possible.

You need to restore back to iOS 5.1.1 using a Stitched IPSW. Follow the FAQ Guide on how to do it (Scroll down to where it says Instructions for iPhone 4, 3GS.... It's very detailed.

Thanks for the answer. I am not sure which IPSW to choose in this step.

click "Custom IPSW", and give it a normal IPSW for your device

I have no ipsw in my computer other than 5.1 which I downloaded yesterday then which one should I choose?

Also I have no saved SHSH blobs, will Tinyumbrella work even if my phone has been restored with itunes?

Sorry but there seem to be so many things. I´ve never tried all this before.
