Apple might be neutral towards third-party iPhone software development, but it's apparently downright hostile when it comes to DIY ringtones -- just 10 days after releasing iTunes 7.4.1, which killed off an easy way of getting your own ringtones on the iPhone, the company has dropped iTunes 7.4.2, which obsoletes the latest ways of getting your own sounds on the phone, including popular apps MakeiPhoneRingtones and iToner. DIY ringtones still make it into iTunes' ringtones folder, but aren't copied over to the iPhone -- a problem we're certain hackers will get around sooner rather than later. C'mon Apple, we know you're smarter than to play these cat-and-mouse games.
