I've updated the OS X Getting Started iPhone modding guide to include the latest firmware and jailbreak methods.
I apologize for the delay in that and the 1.1.2 upgrade and unlock guide I just posted, cash and I have been super busy. That OS X Getting Started link will always have the current Getting Started (jailbreak, activate, install Installer) method. Older guides will change to new URL's as they get older (just the date added on the end of the URL).
Just letting you guys know what's going on...
Cash just got his Windows box set up, so we should see Windows versions of these guides in the next few days.
