ToneCrusher this week has updated its free ringtone content for the iPhone 3G release by offering all free ringtones in the M4R format. Previously customers had to convert the AAC file format (M4A) to M4R on their own computers. Now, all customers are able to send M4R ringtones directly to their iPhone or iPhone 3G or receive these free ringtones via email. We support both versions of the iPhone as the first generation and the iPhone 3G both use the M4R format.
All free ringtones are available as M4R files. ToneCrusher will continue to offer 5 other file formats for all its ringtones including MP3, AAC, AMR and 3GP.
