Phase 1: USB Dumper
Allows anyone with a 3G S right now to generate a file that contains:
- The Exclusive Chip ID tag for your device
- The new RSA signature for a 3.0GM iPhone 3G S iBSS that includes your ECID
This way, if Apple tries to pull a fast one and disallow downgrades to earlier versions, you have a backup that can be used to still allow you to boot an older iBSS.
