How do I change my device locale (default currency symbol) on 3.x and higher?

I want to change my device Locale because some of my apps use my default Locale to determine what currency symbol to use when formatting money values. In Android 2.x, I'd just go to the main Settings -> Language and Keyboard Settings -> Locale but I can't find anything like that in my settings for 3.x or 4.x. Any help is appreciated.
