How Can I Download Ps3 Demos if Playstation Store Service is Not Available in My Country?

So I live in India and the PlayStation Store service is not available in India and SmackDown! vs RAW 2011 demo is coming to PlayStation store pretty soon and I want to check it out before I buy it. Is there any way I can download the game off PlayStation Store?

Suggestion:

I had the same problem so what I did is that I got an american account and downloaded off from there. And for the address part of the account making you write any old address. Then you can download demos.
