Samsung Galaxy S unlocked using own codes
Some resourceful users on the XDA Developers forum have found a way to quickly and easily unlock the Samsung Galaxy S in its various editions to work on other networks. As the unlock codes are located on the phone in a .BAK file rather than a server, all that's required to find them is a simple hex editor script and a USB cable. There is no need to root the phone and, if any warranty needs come up, the handsets can be re-locked to their original providers with the same codes.
T-Mobile's Vibrant and AT&T's Captivate handsets can work on the other's networks, including 3G when the Vibrant is brought to AT&T; the reverse isn't true for the Captivate, which drops to 2G without T-Mobile's frequencies. The easy conversion is supported by the existence of Bell Canada's Vibrant, which already supports AT&T's 3G bands. [via Engadget]
