As most of you know, I have a comparison chart comparing different smart phones by T-mobile. I will only make one post here. If I don't get too responses, I will repost this question at other places.

Does any of the smart phones like the Sidekick, Blackberries, and Microsoft can edit Word and Excel or have an option that you can download to do so rather it's free or paid? Can you provide the link?

What OS each of the phone uses?

Thanks.
