Ambrosia Software has updated iToner, its iPhone custom ringtone transfer software for Mac OS X. iToner 1.0.6 is a free update for registered users. It costs $15.
iToner enables users to transfer their own MP3, AAC, WAV and AIF audio files to the iPhone, and use them as custom ringtones -- without having to pay additional fees.
In addition to iPhone 1.1.3 support, iToner now has French, German and Italian localizations, intelligent audio processing and other fixes and enhancements.
System requirements call for Mac OS X v10.4.10 or later.
