Galaxy S unlocking is cake. Thanks, Samsung

The unlocking of cell phones has become a profitable cottage industry, and if you’ve ever sought to run, say, your AT&T device on T-Mobile’s network, there’s a good chance you’ve stumbled on unlock apps and codes for sale on ebay or one of the many e-commerce sites dedicated to unlocking. Samsung, on the other hand, has stored unlock codes inside a .BAK file on their Galaxy S devices, bringing your gadget’s freedom that much closer…and cheaper.

An xda-developer user has posted instructions at this thread, where you can also see and participate in a poll regarding the success rate of the process on different devices.

Captivate users will be stuck on T-Mobile’s EDGE if they decide to unlock and jump ship, but Vibrant users will be able to utilize AT&T’s 3G. Nice.
