Jailbreaking my old iPhone 2G (Edge version).
It was a bit hard to find software that would still allow me to jailbreak this 2G.
Soooow, I mirrored all I used.
Bootloader: 3.9 or 4.6
Be aware: you will need iTunes 9 (or 8, I guess) — iTunes 10 gives an error: “iPhone could not be restored. An unknown error occurred (1600).”
Follow basic instructions on the PwnageTool (export mode > you need to select the default IPSW) and you’ll get there.
As IPSW you can use the default IPSW iTunes downloads upon restoring. You’ll find the IPSW in ~/Library/iTunes/iPhone Software Updates/ (iTunes 10).
I still had iTunes 9 on my old PowerBook, but I guess you can find the installer on the net somewhere and use a virtual machine or something.
When booting the iPhone in DFU mode, iTunes will find the iPhone in recovery mode. Left click + ALT on the restore button and browse to the custom IPSW.
And, yes, this iPhone 2G is for sale 🙂 Contact me if interested 😉
