Many users have already unlocked their iPhone devices while using the trick found in SAM (subscriber artificial module). Sam Bingner, the developer behind SAM unlock tool, has released a new version which shortens the whole unlock process. This version doesn’t add any new feature or any special support for those users who are not getting the unlock; in fact, new version of SAM removes some activation issues and makes the iPhone iOS 5.1 / 5.0.1 / 5.0 unlock process simpler and easier.
Here Is The Guide:
The first part of iOS 5+ unlock is installing the SAM on your device. Launch Cydia and add the repo “http://repo.bingner.com” by going to Manage -> Sources -> Edit -> Add.
If you have already added this repo in the sources, simply refresh the changes, search for SAM and install it. Before installing SAM, make it sure you are getting the latest version 0.1.16-1.
After your iPhone resprings, insert the SIM which you want to get unlock for in iPhone and tap on SAMPrefs icon which will be added after you install SAM from Cydia.
Now go into the Utilities and press the “Attempt Activation” button. If you don’t see this button, please wait because it may take some time to appear. Once you click on “Attempt Activation”, you will receive the message “Please wait….this may take a while”. Your device will respring after a while and you will see the signal bars.
You have successfully unlocked your iPhone 4, iPhone 4S and/or iPhone 3GS, please make it sure you have saved the activation tickets for that particular SIM on your local machine. The post published here will help you save the tickets in case you don’t know how to do it.
If this method is not working for you, you can also try the manual method.
