We’ve mentioned GreenPois0n before on FSMdotCOM. The tool developed by the Chronic Dev-Team is the one you will use to jailbreak your iTouch 3G. The exploit that was found is in a position to crash the iBoot and continuing in this direction will be able to figure out how to circumvent the protection and enable the Jailbreak.
We are hard at work right now, so sit tight. We plan for the final product to be a program that will not even require the device to be put in DFU, just recovery mode, and it can do that automatically if you plug in a device that is not yet in recovery mode. It will then do on-the-fly patching of the current running iBoot / iBEC / iBSS, decrypt and patch the LLB, iBoot, and DeviceTree in NOR, then reflash them. After this, it will load the kernel from the fs, decrypt and patch it, then use it to boot a very small ramdisk to perform the jailbreak steps that need to be done at filesystem level.
