However, there is a little shortcoming using the Loktar's method Sun albeit it's not a major one which is the method requires you to repeat the unlocking steps each time you wish to use another SIM cards, because each method saves your Ticket. And a manual steps are already given to ease our job saving the Ticket.
But there is easier way, thanks to iPhone Dev team to react fast serving the unlocking community by releasing their Redsn0w 0.9.10b8 to make a Ticket backup that is generated by SAM unlocking tool backup. It takes only one click to backup your Ticket into a zip format for both Windows and Mac.
Backup SAM Ticket by using Redsn0w 0.9.10b8
Step 1. Firstly enable afc2 service. In case you don't own it, then head to ModMyi repo to grab it.
Step 2. Launch Redsn0w and then click Extras Even More and Backup.
Step 3. Now your Ticket will be backed up by Redsn0w from this path: /var/root/Library/Lockdown.
