Review: Coolpad Quattro 4G for MetroPCS
The Quattro uses the stock Android 2.3 calling and contacts applications. One thing I like is that there's a little shortcut to the SMS app from the phone dialer. This means you can type in a new number and then easily start an SMS with that person instead of dialing the number.
The Quattro offers haptic feedback when you dial numbers on the touch display. Call features include mute, speakerphone, add a line, etc.
The Quattro will import all of your Google or Exchange contacts if you have them. Adding Facebook and Twitter friends is optional. Contacts can hold innumerable phone numbers, email addresses, notes, and so on. The Quattro doesn't have any nifty contact widgets for the home screen; only the stock tools are available.

The Quattro runs mostly stock Android 2.3 messaging applications, and doesn't offer anything new or unique.
It has the generic email app for POP/IMAP/Exchange email, and the dedicated Gmail application for Google users. Both of these applications are capable and time-tested. There's also a MetroPCS branded email application that covers basic internet-type email accounts. The stock SMS/MMS app offers threaded conversations, as always.
As for IM, the Quattro has Google Talk on board, and a MetroPCS-branded IM catch-all app that covers AIM, Windows Live, Yahoo, in addition to Facebook and Twitter social networking. The native Twitter and Facebook apps, which aren't preinstalled, offer a better experience, though.
Google's own social networking apps/services, such as Google+, aren't installed. If you use them, you'll have to download them yourself.
