The Samsung Behold II is Samsung's second Google Android device of the United States, the first being the Samsung Moment
The Behold II will be available for T-Mobile and offers 3G support, Wi-Fi, Bluetooth, and GPS. Unlike the Motorola Droid
, the smartphone is running Android 1.5 so you're not going to get some of the enhancements of the newer OS, such as a unified in-box or Google Maps Navigation beta. It'll be up to T-Mobile as to when it will release an OS update for the Behold II as well as some of its other Android devices.
For now, you still get access to the standard Android offerings, like Android Marketplace, Web browser, Amazon MP3 Store, and Google services. The Behold II also has Exchange ActiveSync support.
