I'm having problems choosing the right format to use. I had Guatemala configured, everything was pretty fine even the language, but then I noticed the calendar starting in Monday, here in Guatemala we use the calendar starting on Sunday, I don't know why apple decided to put Monday first. So I selected united states, the calendar is fine but the phone numbers are displayed in a weird form because we don't use area codes. Apple should create a custom region where we could select/modify each setting separately, date format, phone format, temperature and so on. Anyway, does anybody has a table where we can compare these settings without having to test one by one?
