How do I get my word document on my iphone?

I had a patron who was wanting to save his word document on to his iphone, and then be able to send it to others from there. He needed to download an app for this. Here are some options: Documents to Go apphttp://itunes.apple.com/us/app/documents-to-go-office-suite/id317117961?mt=8 it costs $9.99 or you can upgrade to premium for $7.99 more. So, I kept looking for a less expensive option. Another option is the Windows SkyDrive app http://itunes.apple.com/us/app/skydrive/id477537958?mt=8 this app is free. He took the information home with him to try, and I have not seen him to ask how it went. So far, this app is available for apple products only, so android users are still waiting.
