You can purchase the iPhone (via eBay) and run executables against the firmware to "unlock" the phone for different providers. How it's done and difficulty of job are things I have no idea about.
honeslty it's not hard at all... i did mine and i was surprised at how easy it was. Keep in mind i did it for the First Firmware. You dont need to buy it form Ebay just go to the sotre and do everything yourself
