Review: Samsung Dart
Out of the box, the Dart offers little past the basics when it comes to messaging. If you want more than email, SMS, and IM, you have to work for it.
The Dart comes with the stock email/Gmail applications, which are solid apps for most any type of users. Adding accounts to sync is as simple as entering your username and password. The SMS/MMS application is the stock Android variety, and it offers threaded conversations to make it easier to manage your messages. The GTalk application is also stock.
The only social networking application on the Dart is Google's Latitude, which is total weak sauce, in my opinion. The Dart doesn't even offer a catch-all, generic social networking app. It's got nothing. It will sync Facebook, Twitter, and MySpace contacts, but that's all. If you want to actually interact with your social networks, you have to go the Android Market and download the apps yourself.
