AT&T Captivate and T-Mobile Vibrant SIM unlock: an easy task

It’s no news that the Galaxy S is Samsung’s effort of trying to bring some new life to its smartphone line-up. And given the fact that this Android 2.1 smartphone (the Android 2.2 upgrade should arrive in September) was branded in several different ways (the Galaxy S, the T-Mobile Vibrant, the AT&T Samsung Captivate and the Sprint Epic 4G) you wouldn’t imagine that it’s a easy smartphone to perform a SIM unlock on. But think again.

The wizards from XDA hackers found out that the AT&T Captivate and the T-Mobile Vibrant have their unlock codes stored in a .BAK file on the smartphone itself. From there on to developing a way to unlock the phone was just a natural step. Unfortunately, this method has one limitation: while the Vibrant can work with AT&T’s 3G network, the Captivate is limited to T-Mobile’s edge network.
