How To: Save Your iOS 4.0 SHSH Blobs (For Jailbreaking)

For those that want to ensure a trouble-free jailbreak in the future, it is always a good idea to have your device SHSH blobs saved for the current firmware.

If you are running iOS 4.0, then now is a good time to save your SHSH blobs before the iOS 4.1 update. To do so, you can use an application called TinyUmbrella and you do not have to be jailbroken to use it.

Follow the steps below on your PC or Mac with your iDevice (iPad, iPhone, iPod touch) running on iOS 4.
