Samsung Galaxy S Sim Unlock

Now it’s even easier to enjoy your new Samsung Galaxy S phone on the network of your choice, even if it’s the T-Mobile Vibrant or AT&T Captivate version.  The crew over at XDA have found that the unlock codes for the phone are stored on the phone in a .bak file.  Most networks will eventually give you the unlock codes to your phone for free, typically if you are a customer in good standing and have been with them for a while, but if you are super eager to switch today, go ahead and get your unlock codes straight off the phone.  Unlock codes are required to allow the phone to use another network’s SIM card.  Typically, when you purchase your new cell phone from company A, they have it locked in so that you can 0nly use company A’s SIM cards, effectively limiting you to their service.  Well, with an unlock code, you can place company B’s SIM card in, punch in the code and start using company B’s service.

Head over to XDA for all the instructions.  Even if you don’t want to root your phone or void the warranty this method can work for you.  There seems to be different way’s to reach the end goal, so read through the post and select the one easiest for you.  Even better, they are coming up with a one-click method to make it easy enough for anyone.
