PSN account, HELP!!!

This sucks; I have a Singapore PSN account and apparently the games and apps are not that good at all, and then I found out that there's no way of purchasing content from another country's store like say, the US. So seriously, is there any way of changing the country in the account/store or any other way so that I could play stuff from the much better supplied States? Thanks for all the help. And oh, there's no way of getting any real information about how these systems work in the country I'm living in - Indonesia. I hate it when you live in a country who doesn't give proper service to games, and the guys at the Sony stores suck.

I don't believe you can change your country without creating a brand new account.

I'm so sorry for your lose, but the onlt good stuff is really on the ps3, aside from the telly shows and *some* of the psp games. Not most, just some.
