How do I open, edit & save sharepoint documents via mobile phones?

Question

We want the ability to Open, Edit & Save sharepoint documents primarily via Windows Phone, then later also for the other major mobile platforms: iOS, Android and Windows8 phones/tablets.

Where do I start? Can it be done out of the box? Do I need 3rd party solution & if so who is the leader in this space?

Answer 1

I would venture to say you'd want to use Office Web Applications for this. I have used it on iPads before so it should fit the bill. Here's an article from Microsoft specifically targeted to mobile devices.
