Samsung Messager R450

with the voice record feature, are you able to use 'voice recordings' as ringtones?
I am seriously thinking about getting this phone. i used to have a rumor when i was with sprint but had to switch to prepaid. i have upgraded to a touch screen phone that's all fancy, but to be honest that rumor was my all time favorite phone! i am so very happy to find one similar in prepaid land.

thanks in advance
