Save SHSH Blobs (ECID SHSH) of iOS 4 For Windows, Mac. New support from TinyUmbrella has been released to work with iOS 4 on iPhone 3GS also iPod touch 2G and 3G, unfortunately it’s not yet supported for iPad running iOS 4. One more thing this release does not support iPhone 3G since the idevice does not require you to save SHSH blobs, and other older iPod touch MC model!
In case you are going to jailbreak your device in the future, then having SHSH Blobs for iOS 4.0 saved will ease the job in the future jailbreak. Since Apple won’t let you go back down to older firmware versions for your device. Once you ‘upgrade’ they don’t let you downgrade, therefore you need SHSH Blobs
Here is a tutorial on how to save your SHSH blobs (ECID SHSH) of iPhone 3GS, iPod touch 2G/3G on iOS 4:
- Download the newest version of TinyUmbrella (here is for Windows, Linux and Mac)
- Do not forget to use iTunes 9.0 or it’s recommended to use iTunes 9.2
- Run the TinyUmbrella and plug in to your iDevices, such as iPhone, iPad or iPod touch
- Hit on “Save My SHSH” now!
- It will be enabled again once a ticket has been generated to save it to saurik’s server.
You are done! One more thing, you must save the signature for your iDevices (iPad, iPhone or iPod touch) before Apple releases the next firmware!
