iPhone3 - How do I load a ringtone onto my phone???

[FluffyDucks]

Hi All,

Not sure if this is the right spot but I need some help!

I just downloaded a ringtone (its my for my boys then me ) from Cartoon Network from the Regular Show for free.

I saved it to my desktop, saved it to iTunes and is sitting in the 'Tones' section of the Library as well as the 'Tones' section in Devices and my Phone.

I have Synced it but its not showing up under Settings --> Sounds --> Ringtone on my Phone.

What am I doing wrong?

Help!

I download straight from
iTunes on my phone ( search ringtones instead of songs) and it appears in my settings under ringtones
