I have a brand new verizon enV, and I have access to basically all the features it has. I am trying to download an mp3 file to use on my phone, but each time I try it tells me that I am using unsupported content! It won't work for me as a result. Can I change my phone security settings to download my mp3 file? I've already tried downloading via email, internet on my phone, and internet on my computer. what can I do??

thanks!!
