I refuse to pay for an app to rename photos

Question

I work professionally in film and video production and just bought a new 64GB iphone 5 for $399, hoping that it would speed up a lot of my workflow (quickly and easily manage media files and sharing, no annoying bugs and the other things we generally expect from Apple). After a couple days of using it I am totally let down, the main problem being how little control over your own file system you are given in the Apple framework. In my industry I really need to be able to fluidly and reliably send files and info about files.
One problem that belongs to this category that I am experiencing is an inability to rename or at least tag photos with identifying keywords. What if a client or coworker needs a bunch of info that can easily be communicated with photos, but you need to organize them somewhat before sending? You are stuck with a mess of generic names and a bunch of recommendations online for paid apps.
I will say this:
If there is no way for me to rename my own photo files for absolutely free, no strings attached, I am definitely returning the phone on principle! Isn't there at least a free app for this? I am amazed at how unsuccessful my attempts to find one have been so far

Hi,
First, it is a fundamental characteristic of iOS to have no access or control over files.  The very concept of this mobile OS is based on Apps and not files.
Given said this, your post appears really strange to me.  If you do work as a professional in film industries, please tell me you don't rely only an iPhone camera for pictures and movies!  It's definetively not intended for that.  Even I, who's only an amateur, use external softwares to manage libraries and do modification like Aperture or iMovies.
If you want to edit movies/picture took externally and sync to your iPhone, then, you must edit with the software initially used.  If you want to edit movies/picture took with your iPhone, then don't mention you are a professional and like anyone, pay for iPhoto or iMovies.
Mobiles devices are based on the idea of paying per function cheap and small softwares.  A couple of dollards for usefull features should not raise concern up to returning the hardware.  It's more probable that you were looking at the wrong hardware in the first place to fullfill your needs.
And I can tell you, even on a Nikon camera, I don't change Tag nor files names and I'm only an amateur.  You should rethink your process flow.
