You can use software on your computer to unlock your G1.

The T-Mobile G1, also known as the HTC Dream, can be used on T-Mobile networks in the United States, and other GSM (Global System for Mobile communications) networks all over the world. Not all cell providers use GSM technology. If you are traveling abroad and want to save yourself money on roaming, you can unlock your G1 so you can buy a contract with another carrier in that country. You can unlock your G1 in a variety of ways, but one of the popular choices is using a software SIM unlocker on your computer.
