Rejoice, Microsoft Office and iPhone users, because now you can edit, create, and view Microsoft Word files. Dataviz Documents To Go doesn’t bring Excel editing as promised , but at least is here now for $5. The Excel creation and editing will be a free upgrade if you buy now. Like the rest of the Dataviz mobile editors, Documents to Go for iPhone uses InTact, which retains the format of edited files at all times. They also have another version for $10, which also supports Exchange attachments. [ Documents to Go and Documents To Go with Exchange Attachments ]
