If a phone has MP3 ringtones can you upload MP3 files from your PC onto it through a data cable?

Thanks

Yes. (you know messages have to be over 10 characters on DS, i never know what to do with the other seven when the answer is just 'yes.' Any suggestions????)

{deleted as flagpole beat me to it - I was thinking what to put for the other seven characters}

Thank you both! It is very annoying when it says you haven't entered enough characters!! LOL
