Are you wondering how can you apply an official IMEI unlock to your iPhone 4S device without losing your jailbreak? If you are thinking about redsn0w, then I’d like to tell you that this is really not an option as redsn0w does not work on iPhone 4S. So the only option you have is to rely on SAM (Subscriber Artificial Module) to do the job.
SAM is a creation of @sbingner which allows you to deactivate your iPhone 4S officially without using a stock SIM. For those of you who have jailbroken their device using Absinthe, you can follow our step by step guide below.
How to Unlock AT&T iPhone 4S Without Losing Jailbreak Using SAM:
Step 1: Head to your Cydia Store and add repo http://repo.bingner.com and tap install SAM.
Step 2: Go to your settings, select SAM then “deactivate iPhone”
Step 3: First, SAM will deactivate your iPhone 4S. Then when you connect your iPhone back to iTunes, it will activate your iPhone and your device will get unlocked in an official way.
Now that you are done, you can officially activate your iPhone without using a stock SIM.
Those who are not using jailbroken devices you can simply do this in much less steps. All you have to do is tap “reset all content and settings”.
