Save iPhone 3GS, 3rd Gen iPod touch or iPad SHSH Using Windows

AutoSHSHWhen Apple releases a new firmware they don’t like people using older firmware. Sometimes jailbreaking new firmware takes a while and if you ever need to restore to your older firmware it won’t work unless you have your SHSH info. This only applies to the iPhone 3GS, 3rd Gen iPod touch and iPad because they all have a ECID in them which stands for “Exclusive Chip ID”. So, to restore to an older firmware you need the SHSH info for that info and for your device. To backup this info from your device there is a sweet little program called AutoSHSH. This is a Windows only program.

Once downloaded just follow these easy steps:
1. Open iTunes
2. Connect your device to the computer via USB

Saurik Updates Cydia to Display All SHSH Files on File

CydiaSaurik recently tweeted that he has “finished upgrading the in-Cydia SHSH on file firmware display” and “it will now show the full list of on file firmwares.” What does this mean? Apple has made it so you have to connect to their servers via iTunes when you restore your iPhone 3GS. This let’s them approve what version of firmware you are restoring too. Then, they make it so older firmwares won’t restore, which forces you to upgrade.

Saurik has built his own authentication server that you can point iTunes to and then restore to any firmware that you’ve had installed and jailbroken since 3.0. You must approve Cydia to connect to Sauriks servers to store the SHSH authentication file. Previously, Cydia would only show that there was an SHSH file stored for firmware 3.0, but now it will show others like 3.1 and 3.1.2.

This doesn’t affect iPhone 3Gs or the 1st Gen iPhone because only the iPhone 3GS has hardware encryption.
