How to Unlock Samsung Galaxy S Captivate AT&T Android 2.2 Froyo

 

The following is a step by step guide to unlock AT&T Samsung Galaxy S (Captivate) to use on All GSM carriers including T-Mobile. It is fairly long process but I have verified every step on both Android 2.2 and 2.1 and it had worked for me. It should work for you too. This is the easiest method i've found and it does not require you type or modify files manually. So it's safest and you will be unlikely to brick the phone.

  1. Check whether your phone is already unlocked or not. Follow the steps here.
  2. If it is not unlocked. Download and install superoneclick to root the phone. A good instruction video below. You can download the tool from here.
  3. Reboot the phone.
  4. After you successfully root the phone and gain super user rights. Check if you have enough space on the AT&T system partition to make space to install busybox. If you do not have at least 1MB space, you will not be able to install busy box. If you have not installed anything on the system partition, you should have enough space.
  5. Now go to Marketplace download and install the busybox Installer by Stericson. Run it to install busybox.
  6. Now go to Marketplace download and install the app Galaxy_S Unlock by Helroz. Follow the steps in the app to unlock. A good instruction video below:

     

  7. Now your phone should be unlocked. You can verify whether the phone is unlocked with steps described in #1.

Note: If the anything goes wrong. You may hard reset the AT&T Samsung Galaxy S and start over.
