    And back to topic: the answer is no, apple is no longer signing the firmwares for 3.1.3 / 4.0 so you cant go there if you havent back up'ed your device back in the days.

    Actually, for old bootrom devices (iPhone 3G, iPod Touch 2G), you can downgrade to >3.1.3. All you need to do is DFU restore to desired firmware and then use RecBoot to get out of recovery mode. Done it a few times with my iPhone 3G, works perfectly.
