BootNeuter gives you total control of your first-gen iPhone's S-Gold bootloader and baseband.
It's an application you run right on your iPhone that lets you:
- Neuter your bootloader
- Unlock your baseband
- Reflash your bootloader to 3.9BL or 4.6BL no matter what version you're at now (even if you're at 3.8BL)
- Fakeblank your bootloader to let you run serial payloads directly on your S-Gold
