Is SAM Unlock Permanent or Temporary?
There are lots of questions and curiosity about SAM unlock and Loktar_Sun right now. Is SAM unlock permanent or temporary is one of the main question that bothers minds of potential unlockers and the answer probably can make them think once again before unlocking their iPhones using SAM unlock.
The answer is – temporary. That means that this unlock works only for one SIM card unless you save your Activation Ticket. Instructions on how to do that with latest version of redsn0w are here. The main point of this method is to save every carrier’s bundle you use on your iPhone to use it later with SAM unlock. Also, this method will only be active as long as Apple’s servers can be tricked. As soon as they close this vulnerability there will be no more unlocking possibility for those with unsaved Activation Ticket. In other words we can consider it as a semi-temporary unlock for one SIM.
What can you do if you are afraid of losing your iPhone unlock some day? You are free to use Gevey unlock (or similar) to unlock the device permanently. Let’s take a closer look at some of the key points of SAM temporary unlock vs Gevey permanent unlock.
