There are two versions out now! One for Mac and one for Windows:
Mac - Instructions
Windows - Instructions
Notes:
- These links will direct you away from this site and bring you to iclarified.com
- Installer.app is not supported on iPhone/iTouch 2.0 so the tutorials will be for Cydia instead.
- I would heavily suggest staying with 1.1.4/1.1.5 because, in my opinion, the pros out-weigh those of 2.0 firmware so far.
- The instructions work with iPhone and iTouch, though you will have to change certain things appropriately, such as having iTouch firmware instead of iPhone firmware and the firmware links they direct you to are only for iPhone, you will either have to buy the iTouch firmware from iTunes store or get it off of a torrent.
