The Motorola Droid smartphone on the Verizon Wireless network received some good reviews due in part to the updated Google Android (2.0) mobile OS. The Motorola Droid was the first phone to use Android 2.0. Sprint Nextel and T-Mobile USA also use Android but have not upgraded to the new software.
The upgrade to Android offers a performance boost and some new features, such as the voice command turn-by-turn directions for Google Maps. Another feature supported by the upgraded Android OS was the integration of multiple social-networking and e-mail accounts into the phone’s contact list. The camera will now come with built-in flash, digital zoom, scene mode, white balance, color effect, and macro focus.Also, a hugely important feature for the business world has been introduced–Android 2.0 will now support Microsoft Exchange.
