Microsoft is planning on releasing two new native iOS apps using a Metro-style interface by the end of October, an AppleInsider source claims. The first is the Outlook Web App for Exchange 2012 users, also reportedly known as the "OWA Mobile Client for iOS." The app will require both iOS 5 and an Exchange 2012 mailbox, though some offline functions will be supported. Versions for Windows Phone 7.5 and Android 4.0 are planned, but Microsoft documentation is said to list their features as "to be determined," while the iOS app is expected to provide the "best" mobile support.
