Does anyone know if games and applications bought on US sites will work on my phone?

i've always got ringtones, graphics etc. from Jamster.ca but when
I tried to get some games and themes for my new Omnia they told me that all it supported was ringtones and wallpapers.
So I've been looking online and a lot of things I can find say Available in the US only. I would really like to get some software programs like SPB Mobile and some cool games but I'm just not finding much.

I would appreciate any help you all can give me
