How to Jailbreak the iPhone 2G and Fix Cydia! (Working 2020)

Update (2/15/22) - This tutorial still works, but I now have a better one that doesn't require a computer. Here's the link for that: youtube.com/watch?v=1xDrcyDME2A

Today I will show you how to jailbreak the iPhone 2G and fix the following Cydia errors:
"This version of Cydia is no longer supported"
"Untrusted Server Certificate"



You can download the IPSW and redsn0w files here: drive.google.com/file/d/0B0shapseAn0uM2JnYzZZTk…
They are part of a kit to downgrade the 2G to iPhone OS 1.0, but the proper IPSW and redsn0w version is contained in it, just ignore or delete the rest.



 This tutorial works 100% in 2022 for iOS 3.1.3.


This tutorial should also work on the 1st generation iPod Touch, but I have not tested since I don't own one ¯\_(ツ)_/¯ (You would need a different IPSW at least)

Update: I now have an iPod Touch 1st generation, and have made a tutorial on that.
