the author of this app says:
That is what you would have to input in your phone to get John Doe in your address book listing. Red Phone eliminates that long and irritating process. With this program, you can transfer any of the contact phone numbers on your Pocket PC to your mobile phone using the IR port, and they transfer in the format of your Pocket PC contacts.
This application is compatible with nearly all mobile phone models.
