Setting custom ringtone in iPhone

Hi,

I am using a iPhone 4S. I truely believe Apple iPhone is a great technology built by experts.

In spite of, being a great Smart phone, why the setting of custom ringtone, which is very basic feature in any kind of phone, is so complicated?

Can't this be made easier in upcoming releases of iOS?

For setting a ringtone, we have to shorten the length of the song, then create an AAC version. Then change the extension of the file from m4a to m4r...etc...etc

Waiting for a reply...

Regards,
