Hi Everyone! So I was trying to download ringtones for my blackberry 8100 today, and am having some difficulty. I went to tuneusin.com, and whenever I tried to download a ringtone, it would say something about unsupported something or other. Anyone know how to fix this? And also, do I need to download certain software onto my phone for this to work? Thanks for all your help! It is greatly appreciated!!!!!!

just regular old mp3 files will do.
