New Iphone 5s will not mount to iTunes?

I just got my 5s today, I've tried to plugin into my computer, and iTunes won't recognize it as an apple device. I'm running windows 7 and I've tried uninstalling and reinstalling iTunes but that didn't work, I've tried re installing the apple mobile device support driver, that didn't work either and I've tried stopping and starting the mobile device driver I've tried restarting my computer, and none of this works. My phone charges and when I plug it in the message on my phone asking if I trust the computer pops up, I tell it to trust, but still nothing happens. And it asks me if I want to trust the computer every time in plug it in. It still charges though, but my computer sees it as a portable device, specifically a digital camera. So to sum it up, my iPhone won't mounting iTunes no matter what I do. But at least it still charges… Can anyone help me?
