I have successfully changed the phone formating on my iPhone to display Mexico's phone number formating. However, I don't like that the numbers are shown in a "plain" way (55443356), and I would like to add dashes or spaces between the numbers... something like "55-44-33-45".

I've tried editing both the mx and us tags in the UIPhoneFormats.plist, but they remain unchanged... as if added spaces or dashes where ignored.

Is it possible to modify the formating, by adding extra dashes or spaces?

BTW, I'm on 1.1.1

Thanks in advance!
