Ambrosia Software has released a maintenance update to iToner, its software for transferring ringtones from the Mac to the iPhone. It costs $15, and is a free update for registered users.
iToner enables you to transfer your own MP3 or (unprotected) AAC audio files to your iPhone, where you can use them as custom ringtones without having to pay an additional fee, as you do for ringtones you purchase through the iTunes Store.
The 1.0.5 update sports support for the iPhone's 1.1.2 OS release, along with French, German and Italian localizations and other bug fixes and enhancements.
System requirements call for Mac OS X v10.4.10 or later.
