Amazon Prime connection in Singapore

I know Amazon does not provide Prime service to Singapore but is it possible to access Amazon Prime music/movies through a proxy and maintain a subscription?

even if you can do it via proxies, the access speed would slow down significantly.

Yes, I know people who do it in China, which is exponentially more difficult than SG. I have friends in SG (Paya Lebar, represent!) who use proxies for Netflix, so I don't see a problem. You can get pretty decent speeds with Starhub, especially if you have fibre, though speeds off the island are slower, it should be ok. If it doesn't work, just cancel the service.
