I agree that using a VPN (virtual private network) should do the trick if you pick a server that's located in the U.S. There are several free VPNs that should work. They aren't the best VPNs but they should nevertheless work. What these VPNs do is route your internet through other servers in many different countries ( you just pick one, in this case the U.S.) and as a result fool the service you're seeking into thinking you're really in the U.S. Another benefit is that you get enhanced security because your communications is encrypted.
