Does anyone have a recommendation for a good application I can download (preferably free, but not required) for accessing MS Exchange 2010 email on my iPhone 4? Before you say anything, yes, I know I can easily sync my Exchange account with my phone with no additional software. What I'm looking for would be just an app so I can "sandbox" my work email to keep it all separate from my personal mail and calendar. I've had the mail account sync'd to my phone before, but I feel the unified inbox feature just makes everything cluttered, since I receive up to 50 emails a day just in my work inbox alone, not including the emails I already have filtered through Outlook. I've looked at Moxier Mail, but $20 is a bit steep. The only requirement I want the app to do is to be able to sync my mail to the separate app, the calendar function would just be an added bonus.
