ZIP+4 ZIP codes in Contacts for Samsung Vibrant (Galaxy S) I have a Samsung Vibrant (Galaxy S) running Android 2.1-update1.  I have ZIP Codes for many of my contacts in the ZIP+4 format (e.g. 99999-1234). However, the field for ZIP codes does not allow any character except numbers.  Without being able to add a dash it makes it difficult to read (e.g 999991234).  

I would have thought that it would auto-format the number they way it does for phone numbers.  Is there anyway to have the default Contacts program accept ZIP+4 ZIP code format?  Are there any alternative Contacts programs that provide the correct formatting for ZIP+4?  Is the Contacts program standard across manufacturers (e.g. part of the OS)?
It seems that entering ZIP Codes directly in the Contacts app in the ZIP+4 format under Android 2.1-update1 is not possible. However, I just updated to Froyo (2.2) (T959UVKA6).  Not only can the Contacts/ Storage app natively import and export contacts to and from the microSD card, but it also allows directly entering ZIP+4 with the dash in the ZIP Code field!
