How to help the low-income blind or visually disabled get this technology? (see description)

I am a writer specializing in iPhone, iPod and iPad apps. I wrote an app list for the Visually Impaired and found that there are truly amazing apps out there that aid those who can not see.

After publication I heard from many blind folks telling me how these apps had changed their lives.

For those of you who are curious, here are a few of functions of these apps:

GPS apps that guide you, and warn of street crossings.

Apps that tell you what businesses are near you and how to get to them.

Apps that tell you what color things are- excellent for:
Is the banana ripe?
What color is this shirt?
Is the cheese moldy?
Is the sky cloudy?
The cable modem box lights- what color is it?

Apps that warn you of an approaching person. Excellent for work when a person can be startled. Also for security at night.

Apps that tell you which denomination money is.

Apps that have humans that answer questions for you based on a photo almost instantly.

Apps that read web sites.

Apps that detect a light source and as you approach it the signal gets stronger. (excellent if a guest left a light on, burning electricity)

That is just a sampling! There are more too!

But recently I learned that many visually disabled people are not only unaware of this technology, but that they could not afford it if they were.

Are there any charities out there that ask for donations of iDevices to recondition and give to the visually disabled? (outdated is fine so long as it has a camera)

I know I have an old iPhone 3Gs and am going to load all the apps on it and send it out to someone who contacted me. But I was wondering if anyone does this yet and if it would be feasible to start such a charity if not?

Is it expensive to set up a charity? I am totally broke.
Would it have to be set up as a charity?

I need help brainstorming this out Jellies!
