The Z-Zone application allows you to put contacts that you rarely use or dont want to accidentally call into a Z-Zone at the end of your contacts list.
By prefixing selected contacts with "Zzz" they will be taken out of the way of your normal contacts.
You could do this yourself; but, it’s tedious work. The Z-Zone application makes it easy to enter and remove contacts from your Z-Zone with a single click. This application also makes it easy to navigate your contacts once they are in the Z-Zone.
