This works…sort of. My 3GS was at 3.1.2, I have a 3.0 SHSH with Cydia – I followed instructions and it did exactly as advertised – including redsn0w 0.8 JB. Problem is that after the downgrade and JB the phone will not activate – no signal at all.

I went back to 3.1.2, phones works perfectly. Downgraded again, and again, smooth process – but no activation, no signal.

Any ideas?

Same problem here – Day 1 3gs, “The iPhone could not be restored. This device isn’t eligible for the requested build.”

If anyone is having problems saving the “Host” file with the address block follow this. First off to explain why it’s not saving is because we are not the “owner” of the folder, your cpu system is. So to change this follow these instructions.

Open Finder, go to “Go” then scroll down to “Go to Folder.” Type in /etc/ then hit enter. Change the “View” to Columns if your not already. Click on the “etc” to highlight the folder then click the “ctrl” button. Select the “Get info” (If you see a “lock-icon” click it to unlock so you can make changes. Go down to “Ownership & Permission” Click “Details” to bring down list. Under the “Owner” change to your name or whatever name the computer is named which your using. Close then open “Host” file to type in block address and you should be able to save.

awesome. This worked. I had internet tethering than stupid 3.1 “ruinz it”. Just to follow up, this guide didnt work out for me. What i ended up with is an Iphone in recovery mode…and it wouldnt get out. So i searched on the internet for how to get out of recovery mode and it gave me a reset non activated phone. I opened itunes…And i think this part is the key, I made a backup of my phone with firmware 3.0 a while ago probably when i upgraded it. But in this mode, basically wiped free, it allowed me to restore to that backup. and back to iphone 3.0.
I have an iphone 3G not S
So steps.
1.)Get into recovery mode.
2. Do the reset procedure.(i DONT KNOW IF QUICKPWN HAD anything to do with it but i opened quick pawn and it told me to do press home+power button for 10 seconds, then press power button for 2 seconds) so i dont know if quickpwn deleted evertyhing or if its that little 2 steps but it gave me a non activated phone screen.
3. Opened ituned and restored from a backup.

Just to recap, i already had a backup. So this may work for those with a totaly not working phone after trying the different downgrade guides on the internet. And i never gave up to the idea of getting 3.1.2 firmware cuz who knows what else att is going to block next.
Iphone 3.0 for life…..UNLESS the guys at http://help.benm.at/help.php figure out how to get tethering to work on newer firmwares.
