    - iPhone 3G devices can be easily downgraded to iOS 4.1 and 3.1.3 using Legacy iOS Kit, with the option to jailbreak and hacktivate
    - For iPhone 2G and touch 1, here are 3.1.3 custom IPSWs that may be useful: https://github.com/LukeZGD/Legacy-iOS-Kit-Keys/releases/tag/jailbreak
    - IPSWs for older iPod touch are not available in ipsw.me. They are available here: https://invoxiplaygames.uk/ipsw/ and https://archives.legacyjailbreak.com
