Sam has a mobile phone and wants to download ringtones. Leo says that ringtones are a huge business and people are buying ringtones of songs they already have. 1/3 of all music revenue was from ringtones. He shouldn't have to pay again just for the ringtone. It's really easy to create a ring tone from a song he already has. It's just a music file stored in a special directory.
Leo downloaded RingDroid, an app which would allow him to create a ringtone from part of a song he chooses. He can then clip it and save it to the ringtone directory. On the iPhone, he can actually create them in iTunes.
For a feature phone, there is no "app" to do this. There is third party software, like BitPim though, but it's not as dependable. Leo says to avoid the so called "free ringtone sites", because these are scams.
