Transfer mp3 to Krazr for your own ringtones...
Surely they allow you to set your own, custom updated mp3 ringers.
its very simple since you have a motorola, get yourself a USB cable and a copy of Motorola Phone tools......all you have to do is install phone tools, connect your phone, enter the multimedia studio where you can customize pictures, edit song files so you can use them as ringtones, (change the balance of the songs and the way it begins and ends), you can make a video real of you pictures with songs, and at your voice on top of it.....back up your phone book on your computer, update your calender, and use your phone as a modem for your computer.....
