Backup your iPhone SHSH Blobs, before the spirit jailbreak

The Dev Team will soon be releasing an iPhone 3.1.3 jailbreak without tethering. I’ll update this post as soon as the update is released. However this jailbreak is a userland jailbreak called Spirit. This is a jailbreak not an unlock (unlock means you can use the iPhone on tmobile also). A userland jailbreak is a security hole that was found and being used to jailbreak a phone. Apple will usually patch such holes in a day or so by releasing a new software update (like maybe 3.1.4). So before the jailbreak is released, and apple updates the firmware on their site, you will need to backup you SHSH Blobs. This will allow you to restore to an older software version, in case you need to erase your iPhone, or somehow you accidentally upgraded. Once a the new software version is released, and you need to restore your iPhone (or accidentally upgrade), it will only restore to the latest version provided by apple. The latest version may not have a jailbreak though, so you’ll be screwed. However you can bypass this if you backup your SHSH Blobs. Once Apple releases a new software version you can no longer create the SHSH Blobs for the older software  version, even if you didn’t upgrade.  To backup you need a software called umbrella, and your phone’s eccid. It’s not complicated

1. Get your iPhone’s eccid, to find out how to do that click here.

2. Now download umbrella, by going here.

3. Now run the exe, or dmg depending if you are a mac or windows user.

4. Put in the ECCID you got from step 1.

5. Choose 3.1.3 (or whatever the latest version is that’s jailbroken), and pick apple.

6. Find the file that was saved, and keep it somewhere safe, you will need it in the future.
