Pneumonia is a application created by GreySyntax and GRMrGecko] to aid in booting and preparing the iPhone2,1/iPod2,1/iPod3,1 for restore. This utility is a port of iBooty & Payload Pwner. This utility replaces the old method described on OpenPwn (See notes).
To use this utility you must have saved 3.1.2 SHSH's or be on 3.1.2. A Mac running OS X 10.4+ A custom 4.0+ restore with the NOR flash disabled.
This application will extract both the 3.1.2 & custom IPSW and saved your patched files in "~/Library/Application Support/Pneumonia" + stock firmware md5 sum. This allows the application to support multiple devices and prevents it from having to extract the IPSW upon every application launch.
