Apple has released an update to iTunes that blocks users from creating free custom ringtones and then syncing them to an iPhone. Despite Apple's best efforts to thwart users, a workaround has already been found and posted to the Internet. A method of using iTunes to create ringtones for the iPhone using songs not purchased from the iTunes Store was first posted by Macrumors.com on Friday. Users confirmed after installing iTunes 7.4.1 last night that the method no longer worked.
However, an Engadget post on Saturday details a workaround for the update, again allowing the free ringtones to be synced to the iPhone
