Apple iTunes has been updated to block users from creating free custom ringtones and then uploading them to anApple iPhone (reviewed here)..

Despite Apple's best efforts to thwart users creating iTunes ringtones for iPhones, 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 on Friday. Users confirmed after installing iTunes 7.4.1 over the weekend that the method no longer worked.

However, an Engadget post on Saturday details a workaround for the iTunes update, again allowing the free ringtones to be synced to the iPhone.

When Apple first announced the ability for users to create custom ringtones earlier this week, it was meant only for songs purchased from the iTunes Store. Users would have to pay an additional 99¢ for the ringtone.

Third-party applications such as Ambrosia Software's iToner have been updated to work with iTunes 7.4.1 and is available from the company's website.
