Samsung SGH-P107

Well I was trying to get a ringtone for my phone via the Wireless Interent feature and when I downloaded the ringtone and attempted to save it, it said that my memory was full and that I would need to clear up space. Well According to my memory status, my phone has 30/500. I have already downloaded some other ringtones and would like to know if it is possible to delete them so that i can make space for this new one. Thanx a bunch ^_~
