It was a very slow day, but we have a bit of breaking news tonight.  Engadget is reporting that Dagentooboy of XDA-Developers has discovered that the codes used to unlock the Samsung Galaxy S are not stored in a remote server, but in a .BAK file on the device itself.  The codes are in fact so simple to find that all you will need is a hex editor and be able to key right in when inserting a new SIM card. While I have not personally tested this method, Engadget reportedly unlocked both the Captivate and Vibrant in less than five minutes  time.  The other interesting part about the unlocking was that the T-Mobile Vibrant was capable of AT&T 3G using an AT&T SIM card. Quite surprising indeed.

So, do you want to know the best part? Well, that is that none of this requires you to actually root the device.  That’s right, you can do this on good old stock. The other bit of good news is that you can re-lock the handset with the very same code. It is all very easy and quite safe.

Anyone out there considering ditching T-Mobile for AT&T and taking their Vibrant along for the ride?
