Last Sunday, we relations a new method to unlock your iPhone (iPhone 4S included), no matter its baseband using SAM on Cydia (read: UnlockediPhone 4S and iPhone 4 available for any baseband ). However, although simple if you follow the instructions, the procedure proved to be a bit "long" and not allowed to use only one SIM card. But that's ancient history. With the update of Sat , the procedure is faster, allows multiple SIM cards and eliminates the need to have a computer. Now, just insert the SIM card you want - that the iPhone is not supposed to use.
Once done, simply run "SAMprefs" on the springboard> Utilities and click on "Attempt Activation". Let the iPhone work for several seconds. Once everything is up, the phone will respring and the task is completed.
To use the original SIM card, or otherwise, repeat in order and everything works like clockwork.
