Friendex description

A Pokedex themed contacts app to view, edit, sort, and contact your friends.
You can view info on your friends that is stored in your phone contacts, including phone numbers, email addresses, Area (where they live), and Cry (their custom ringtone).

Area will usually be unknown unless you edit the contact (pencil icon on info tab).
Cry will default to your default ringtone, and can be changed by clicking edit.
