If you are using a GSM phone, you can also use P2KTools ..easy to find at most
forums that deal with cell phone mods. But you really only need that or similar
to load the ringtone on the phone or to make backups of your contacts / phone #'s
Also any audio editor program can make whatever you want into a Ringtone.
You only need to know which format your phone wants .. Usually MP3 or .WAV
and you need to make it the proper time length. Usually no more than 20 seconds
Note: This app Does Not Work on a CDMA type phone, such as used by Verizon
Wireless or Sprint
