Sending own Ringtones...

Hey All-

I have a ringtone in Keypress, Composer, and RTTL format. I cannot enter this ringtone into the composer because it is too long to enter. It must be sent to the phone. My question is ... the ringtone I have is only available on european sites. So you have to have a European phone. I do not and was wondering if there is a way to send either the composer or RTTL format to my phone myself. I do not have a link cable, so I was hoping to do this over text messaging or some means by that ... Anyone know if this is possible.

Appreciate the help,

-Grand
