Review: Huawei Prism for T-Mobile
The Prism doesn't stray too far from the beaten Android messaging path. It offers the same core functions found on most stock Android devices.
The stock email, Gmail, SMS, Google Talk, voice dialer, and voicemail applications are representin'. I was unable to find any differences between what the Prism's version of these apps offer when compared to any other Android device. They all work well.
CMAS is installed, which will deliver emergency alerts to the Prism via text message. The alerts include warnings about severe weather as well as Presidential alerts about serious threats and emergencies. You can opt out of some of the lower-grade threats, but not Presidential alerts.
On the social networking front, Facebook is pre-loaded, but Twitter is not. Facebook can also be integrated into several services on the Prism, such as the contacts app. Google's Latitude app is also on board, but Google+ isn't.
