Review: Samsung Exhibit 4G
The Exhibit 4G offers the same stock Android messaging apps as found on the Dart and Gravity Smart, but, puzzlingly, it ditches T-Mobile's Group Text and Cloud Text features.
There are three email programs (Gmail, Email, T-Mobile Email) from which users can choose. I still prefer the native Gmail app, though the generic email application works fine for non-Gmail email services (such as Exchange).
The SMS application offers threaded, conversational texting and the GTalk application serves as the Google instant messaging client. You'll need to hit the Android Market to find support for AIM, Windows Live or Yahoo IM.
Facebook is pre-installed, but Twitter isn't. Google's Latitude is also pre-installed, as are some catch-all social networking applications from Samsung. The catch-all app can access Twitter, Facebook, MySpace, and RSS if you want to get all your updates in one place.
The Exhibit 4G is pre-loaded with Qik's video chatting service, and includes a user-facing camera to use with it. My experiences with Qik continue to be hit-or-miss, and it can only be used with other Qikkers.
