Why doesn't my Desire S support RTL?

When I bought my Desire S in Israel I was under the assumption that it's OS (Android 2.3) came with built in Hebrew support. When I turned the phone on I discovered that there isn't an option to choose Israel as a locale and that I don't even don't have a Hebrew keyboard. That doesn't bother me (despite the fact that it should be supported) as much as the fact that even after I downloaded a Hebrew keyboard my SMSs and other little things in Hebrew appear left to right and not right to left (RTL). What can I do to make it appear in the correct RTL way?
