Installing the English (United States) language I recently got my Desire HD, and it came pre-installed with Deutsch, English, Spanish, French and Portuguese, each in a (Spain) or (Portugal) flavor. Is there some way of getting an English (United States) or English (United Kingdom) on it?
 Removing the other languages as well, would be nice.
Android's language/locale/internationalization support is pretty bad at the moment.  I'd recommend flashing a US or UK ROM on it, which will have the language built-in.
