I want to put in a 15hour audio file in my Iphone?

How do i do this? I tried with itunes but it won't work. I have enough space in my phone to fit the file, but i can't get it into my iphone in any way. :[

If it's not possible, is there any site that allows me to upload + listen to my 400mb 15hour audio file?
