VITO have just updated their
RingtoneEditor software to version 1.2. It's really easy to use - just load up an MP3, then click play and choose the start and end of the ringtone. The new version brings compatibility for Samsung BlackJack and MotoQ users too.
Once you've chosen your start point the software will begin replaying a short part of the song from your chosen spot so that you can increase the accuracy of your start point. Once done you repeat the process for the finish point to ensure that the best part of your MP3 is played out when your phone rings.
