Review: Samsung Rugby Smart for AT&T
The Rugby doesn't deviate from the norm when it comes to messaging. All of the stock Android messaging applications are on board, including email, Gmail, text messaging, and Google Talk. They all work without any trouble.
As for social networking, the Rugby comes with Samsung's Social Hub. This can be used as a catch-all app for Facebook, Twitter, and LinkedIn. It will channel all your status updates through this app, as well as private messages from each of the three services. You can use it to post a status update, as well.
There's a separate IM application on board, too, which plays with AIM, Yahoo!, and Windows Live if you want.
The native Facebook app is preinstalled, but Twitter is not. You'll have to snag that from Google Play (née, Android Market). The same goes for Google+; it's not pre-installed, but is available from the app store.
Qik is available if you're into the whole video call thing, but your friends/family will also need to have Qik on their phone to make it work. Qik doesn't play nice with FaceTime, Skype, or any of the other video calling services out there.
