If you have a mobile phone then you can almost certainly make your own ringtones from mp3 files.
If you have an iPhone, Apple make it complicated but it can be done - see this - http://www.youtube.com/watch?v=90DUh6KgZSA
I have a synthesizer up here in my attic, I decided to make some tones with it. They are yours to download and use as your ringtones.
All files are edited so they will loop smoothly.
I hope 2013 treats you all well,
