Apple has released new versions of its three productivity applications as universal apps, so iPhone users can now create and edit documents on the go. Keynote, Pages and Numbers were previously touch-screen optimized and available for the iPad. Now iPhone owners who already have the software on their iPads can upgrade for free.

For everyone else each individual app in the suite costs $9.99. Keynote is Apple's answer to Microsoft Powerpoint, while Pages and Numbers handle word processing and spreadsheet functions. The products import and save documents in Microsoft compatible formats, although many enterprise users are still looking to Microsoft to create mobile versions of their software.
