The XDA Developers forum is one hell of a place where most of the unlocks and roots for the current crop of smartphones are discovered. Now a member from the forum has discovered a pretty simple way to decipher the unlock code for all models of the Samsung Galaxy S (including Captivate and Vibrant) – the codes are reportedly stored in the phone itself. And the best news to have emerged is that all of this can be done without the user having to actually root the device. If you are looking for a root, you are welcome though. Check out this Samsung Galaxy S root guide I had posted earlier.
There are a few dangers though. The phone can potentially freeze and it is entirely up to the owner to take the risk. Nevertheless, the unlocking method will take less than five minutes if done correctly. Also, you can use the same code to lock your device back. So, it’s all very simple stuff.
