iPhone2,1 3 1 7C144 Custom Restore ipsw

You can use this custom ipsw to upgrade to jailbroken 3.1 on your iPhone 3GS (useful if you are on Windows since the Pwnagetool only works on Mac).



Note: This will only work if you are currently running jailbroken 3.0/3.0.1.



The configuration for this ipsw is:



No custom logos

No activation (correct setting for ATT phones that are already activated)

No Icy

No extra cydia packages

No unlock/bootneuter

608 MB boot partition



To use just put your phone in recovery mode and alt/option click on restore in iTunes and browse to this file.



This does not update the baseband so you can still unlock with ultrasn0w if desired.



If this is useful to you please seed, thanks.
