Been looking all over the net for this 'fix' that can be done to get custom ringtones on my iphone, all sounds really complex, thing is I managed all the complex stuff apart from re-naming my 39sec music file from an AAC track to a .m4r file. that bits supposed to be easy peasy but I don't know how to rename a file type...just its name.
I have windows xp.
