DataViz has released a major update to its premium version of Documents To Go to add support for editing PowerPoint presentations and editing and viewing supported attachments from Gmail directly on the iPhone. Formerly known as Documents To Go with Exchange Attachments, the rebranded Premium version now permits users to edit and create PowerPoint presentations directly on their devices, including support for editing and adding bullets, text, and speaker notes as well as sorting, adding, duplicating and deleting slides. The new version also allows users to access attachments directly from their Gmail accounts for viewing or editing directly on the device. Documents To Go Premium continues to support viewing and editing of Microsoft Word and Excel formats as well as enhanced viewing of PDF files. Documents to Go Premium 3.0 is available on the App Store for $15 for new users and is available as a free upgrade for owners of Documents To Go with Exchange Attachments. DataViz also provides a standard version of Documents To Go 2.1 with only Word and Excel editing and no attachment support for $10.
