I must once again confess that I'm a total ringtone Luddite. Yup, I'm still rocking Marimba! But for those of you with a Mac who want to kick it old school or drop the latest hawtness straight onto your iPhone, PocketMac brings you RingtoneStudio:
...easily create ringtones from practically any multimedia file -- from QuickTime movies to unprotected music files of all types. What's even better, there's no crazy iPhone hacking required. Your iPhone doesn't even have to be connected when you're creating your ringtones.
If any of you iPhone ringtone DJs decide to give it a whirl, let us know how it works for you!
