    Apple not signing firmwares is not a concern for 3G phones.

    You may download iOS 4 ipsw from the downloads section here on MMi then in iTunes click shift+restore and select the ipsw you downloaded. That way you wont have to go up to 4.0.1.

    Umm yes it fails if you have a 3GS. But you dont...so Apple doesnt need to verify the restore and sign the firmware.

    Because you have a 3G you should Shift + Restore to 4.0, and if you get the recovery mode loop, just download iRED from iH8sn0w.com | Jailbreak your iPod touches and iPhones and follow the instructions of Recovery mode loop. Or you can go to 4.0.1 anyway, seeing as it is jailbreakable for iPhone 3G still.

    1) no need to restore, just run RedSn0w again with options deselected.
    2)You could upgrade to 4.01 and use RedSn0w to JB (point at 4.0 ipsw)

    Well after numerous attempts I must say apple is now verifying and signing 3G ipsw's. I finaly gave up, used 4.0.1. And it verified and restored perfectly. Thanks to all who replied with the 4.0.1 info. All is well in dream land.
