- ^ a b c d e A maliciously-crafted TIFF, using the libTiff Exploit, loaded into Safari, can be used to jailbreak iPhone OS 1.0-1.1.1. There are several of these TIFFs available - two of the most notable include planetbeing's and AppSnapp. However, both of these services are now offline, so cannot be used. Even so, a user could still create their own TIFF and payload in order to jailbreak 1.1.1, such as by following this guide.
- ^ It was previously possible to jailbreak 1.1.2 using OktoPrep alongside touchFree. However, the original package repository for OktoPrep through Installer.app has been taken offline. A user would need to find the original package file for OktoPrep and install it manually in order to jailbreak 1.1.2.
- ^ It was previously possible to jailbreak 1.1.3 using Soft Upgrade, but this is no longer possible due to the package repository being taken offline. A user would need to find the original package file for Soft Upgrade and install it manually to jailbreak 1.1.3 using this method.
