There's new hope for Android aficionados who want IT to let them use their preferred mobile OS for work, thanks to Motorola Mobility's four business-oriented smartphones: the Photon 4G and Xpert for Sprint, Atrix 4G for AT&T Wireless, and Droid 3 for Verizon Wireless. Motorola has filled in several deficiencies of the Android operating system that keep many IT organizations from allowing its use. For example, the new Motorola devices add support for on-device encryption to Android 2.3 "Gingerbread" and support more Exchange ActiveSync (EAS) security policies, so they're now compliant with many organizations' security requirements.
