A good friend of mine recently got an iPhone and she had to call "Tech Support" (me) to figure out how to get a frackin custom ringtone on her phone. Honestly, I hadn't done that so I said to myself, "how hard could it be"? Boy was I surprised! Most phones allow you to buy ringtones right on the phone! Well after 30 minutes on the phone with her, we finally got her ringtone. We had to go through iTunes on her Mac, and could only select "certain" tracks, then had to pay for the song and for the ringtone! After attempting to sync the ringtone onto the iPhone unsuccessfully, we discovered that her Mac had not been "authorized" to play that particular track. After authorizing it, things finally worked. She asked a simple question, "why do I have use my Mac to buy a ringtone? I can't use the iTunes on the iPhone? That's kind of stupid". Well it is.
