Electric Pocket’s Ringo Mobile ringtone manager is now available for users of the Treo 700w smartphone devices based on Windows Mobile 5.0. Ringo has long been the best-selling ringtone manager for Treo smartphones based on the Palm OS–and more recently devices based on Pocket PC Phone Edition. Ringo Mobile enables users to easily assign MP3, WMA, or WAV format ringtones to every incoming call they receive on their Treo or Pocket PC phone. Ringtones can be assigned to individual callers or to groups of callers–such as business, family, or friends.
