The HTC Salsa just like the HTC ChaCha offers a one touch to Facebook button. "The Facebook button on HTC ChaCha and HTC Salsa is context-aware, gently pulsing with light whenever there is an opportunity to share content or updates through Facebook. With a single press of the button, you can update your status, upload a photo, share a Website, post what song you are listening to, ‘check in’ to a location and more." The Salsa smartphone also comes equipped with Android 2.3.3 (Gingerbread), a 5MP camera with auto-focus, flash, and VGA front-facing camera just like the ChaCha.
