ha ha ha, was that a 'dig' at orange?! if you dont know how to use pc suite (or your phone) yet, why dont you buy (or borrow) a card reader? that way you can literally 'drag and drop' mp3s straight onto your memory card, bang it into your phone and youre away.
im sure if you search the net, you'll find a download site where you could get a copy of the tune you want, theres enough of them about
youve got my mind wondering now... what tune are you trying to get? PM me if your too ASHAMED to post it openly! ha ha ha
