iOS 5.1 Jailbreak: How To Use RedSn0w 0.9.10b8 To Backup Your iPhone's Unlock Activation Ticket [VIDEO]

After Chinese researcher named Loktar_Sun discovered a method that allows unlocking any model of the iPhone on any baseband with the help of the Subscriber Artificial Module (SAM) by Sam Bingner, iPhone Dev Team also joined in the party by releasing RedSn0w 0.9.10b8, an updated version of the jailbreak utility, allowing users of the SAM to unlock the tool to back up their activation tickets for safekeeping.

As mentioned in the process of unlocking the iPhone using SAM, users were required to manually backup activation tickets. But thanks to the latest version of RedSn0w, saving the unlock activation tickets has become even easier. RedSn0w 0.9.10b8 has the ability to backup arbitrary directories or files into a zip file on your Mac or PC.

Before going to the steps, let's take a look at what the iPhone Dev Team has to say about the update:

Update #3: redsn0w 0.9.10b8 adds the ability to backup arbitrary directories or files from your device into a zip file on your Mac or PC. The new button is Extras>Even More>Backup and it requires your device to be jailbroken with the afc2 service enabled (most jailbreaks include that). By default it will backup your activation records from /var/root/Library/Lockdown, which is useful for everyone taking advantage of today's SAM unlock using Loktar_Sun's trick (more on that in a later post!).

Update #3b: The 0.9.10b8b update to redsn0w makes the zip files more compatible with the native Windows explorer (which doesn't like leading slashes in the filenames).

Below are the steps to follow. Users should make sure that their iPhone has the afc2 installed most jailbreaks like RedSn0w and Corona include this by default. It can be grabbed from the ModMyi repository in Cydia.

Step 1: Open RedSn0w 0.9.10b8 and click Extras > Even more > Backup.

Download RedSn0w 0.9.10 beta 8 for Windows

Download RedSn0w 0.9.10 beta 8 for Mac

Step 2: Leave the default directory in the Please a path to backup field, and click Ok.

Step 3: RedSn0w will save off a timestamped zip file of your /var/root/Library/Lockdown directory to the same location where RedSn0w is installed on your computer.
