We’ve got some big news for Microsoft Office users who just so happen to own an iOS device. The top-selling business suite is now available for iPhone.

Office Mobile brings Word, Excel, and PowerPoint to the iOS universe for the first time. With it, users are able to create and edit Office documents, and share them via email, or through SkyDrive or SharePoint.

According to Julia White, marketing manager for Microsoft Office:

With Office 365 Home Premium and Pro Plus, we promised they’d work across all of your devices. Now that those are out, it’s time to expand think about other end points our users have said are important to them.

Key features include:

  • Cloud – With your phone, you can access Office documents that are stored on SkyDrive, SkyDrive Pro, or SharePoint.
  • Recent Documents – Office Mobile is cloud-connected. The documents you’ve recently viewed on your computer are readily available on your phone in the recent documents panel.
  • Email Attachments – You can view and edit Office documents attached to email messages.

Take a look:

The new app is free to download in the App Store. However, the service is only available to Office 365 Home Premium and Office 365 ProPlus subscribers.

The iPhone version doesn’t count against a subscriber’s five supported devices. A single account will support up to five iPhones.

It has long been rumored that Microsoft was working on an iOS version of its Office suite. Those rumors focused almost exclusively on an iPad version.

On whether Office would soon be arriving on Apple’s tablet, White would only note:

With the small screen, it makes a big difference to have a native application … With a tablet, you have more screen space to work with, so Office web apps provide a great experience there.

It sounds like a native iPad app is a long way off, no?

Office Mobile is available in the App Store.
