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?

What app can I download to get copies of all texts/calls my husband sends/received?

So the background is last year he had an affaire, and hasn't done anything for me to rebuild our trust. When I've looked at his phone I've seen texts I didn't like, but he made a comment yesterday during a fight that he cleans up any loose ends when he s being unfaithful, and the stuff I do see is because "he doesn't care about those"

We have two kids together, and IIm absolutely heart broken. Long story short, IIm done wasting time. He tells me one thing, but I fear he does another. Really need to know if he is truly being honest now, or if he is continuing in his ways.

I've used the programs that retrieve deleted texts, but they don't pull everything for some reason. I've tested it by sending a text from his phone to a text app, and replying and neither texts showed on any of the apps.

What are some applications for an IPhone that I can download on his phone to keep tabs on who he s talking to?

If anyone knows of any free apps that send a copy to my phone please let me know!

All the ones that look promising are costly.
I need some peace of mind

Iphone 5s Virgin Mobile activation issues. Null?

I have been trying to activate a new iphone 5s for Virgin Mobile. I have tried to activate it online and keep getting the message that 'null is required'. I can't find any explanation to what this is or how to remedy the problem so I can use my new phone. Does anybody have any ideas as to how to fix this?

My audio jack in my iPhone 6s isn't working?

When I plug my headphones into the headphone jack and try to play music it doesn't work and all you hear is this weird noise, and when I try to watch youtube videos or anything else there's no noise at all. I'm really worried since the iPhone is brand new and I have never had an iPhone before.
