Unfortunately, you're going to have to fork out for Office 365 if you want to get in on this action.
Microsoft has finally announced the availability of Office Mobile for iPhone users. Redmond revealed the news via its Office News blog, explaining that the release of Office Mobile is part of its commitment to delivering regular updates and new capabilities to Office 365 users. As such, the application will be free to those that already subscribe to Microsoft's Office 365 online services suite (Office 365 Home Premium costs $100, or $10 per year).
Using the app, iPhone users will be able to view, edit, share, and create documents straight from their phone. Microsoft's announcement pushes consistency in a big way, harkening back to its recent ad campaign where it slammed Google Docs for messing up formatting for users. The company says support for charts, animations, SmartArt graphics and shapes will keep formatting and layout intact when iPhone users are viewing, editing, or adding comments.
While Office Mobile for iPhone is free for Office 365 users, there's no option to purchase the app if you don't subscribe to Office 365. Check out the demo below for a taste of what Office on your iPhone looks like.
