Unlock iPhone 4 / 4S On iOS 5.0 / 5.0.1 / 5.1 On Any Baseband With SAM


by cM Boy on April 22, 2012

Unlocking iPhone 4 and iPhone 4S has become much easier due to a new method known as SAM package unlock. It has been released to the public and available for use. SAM can unlock your iPhone 4S and iPhone 4 running iOS 5.0 / 5.0.1 / 5.1 with any baseband.

We have tested it on our devices and it appears to be running fine. iPhone Dev Team’s key member MuscleNerd has also confirmed that SAM is working properly.

This method is discovered by Loktar_Sun by exploiting a logical bug in Apple’s server. You need to have a jailbroken device in order for this method to work because it involves package installation through Cydia.

How To Unlock iPhone 4 / 4S On Any Firmware With Any Baseband:

STEP 1: You need to have a jailbroken iOS device. If you are already enjoying a jailbroken device then just skip to the STEP 2. If you don’t have a jailbroken device, you can easily jailbreak it by following the guides below:

STEP 2: First of all you need to add a repository in Cydia.

  • Open Cydia.
  • Goto “Manage” at the bottom.
