Microsoft is planning an iPhone version of Office, if you believe the President of Microsoft Business Division, Stephen Elop. He has hinted that Office might be making its way to Apple’s smartphone sooner, rather than later.
Several unofficial solutions are available – Quickoffice being the most recent – but officially, users can only read Office files – not edit them. There’s no Microsoft app.
When questioned further on how soon an iPhone office client would be available, Elop took a step back, saying “not yet, keep watching”. in the meantime, users will be provided a web version of Office over the next couple of years, so hold tight for that.
