is there an app to customize the date format displayed. i want yyyy.mm.dd. the only built-in way to do this is to change the region in settings to another country. but that also changes the language to match the country for the days of the week and other things. right now i've set it for the uk (but i live in the us), which does dd.mm.yyyy (close, but the reverse of what i want). but certain things are changed as well, like the default settings for addresses in contacts is set to uk address conventions. why does apple not allow you to set the date format independent of the country you live in?
