MotionApps has released an update to its mRing software. mRing is a ringtone, profile and call manager application for Treos and the Centro. It allows you to assign MP3, MIDI, WAV ring tones and custom full screen pictures to your contacts and contact categories, to define and schedule profiles (silent, meeting, loud etc.), filter incoming calls and define blacklists and much more. The latest update features support for the Centro and Treo 755p, adds a filter to browse by contacts, fixes a few bugs and minor UI updates.
