How to set up phone number formatting

[Raymond Moul]

I can't seem to find any way to set the phone number format on my United States, AT&T, HTX 1x.

I'd like to have the phone show the dashes in between the numbers when someone calls or I look up a contact's info in the contact app. Something like 5-555-555-5555 would be awesome.

Does anyone know how to set this up?
