Exchange Online supports a vast amount of mobile devices, and even offers BlackBerry integration for free via RIM’s cloud offering (BBCS).  So whether you use iPhones, Androids, or BlackBerry devices in your business, you can still integrate with the Office 365 system.  You can also mix and match these devices, as mobile device access is free with Office 365.
