Send/receive SMS, make calls, locate your phone via GPS, activate WLAN or Bluetooth, etc. It can be useful for those who prefer typing SMS on a real keyboard. The app also notifies you about new "events" on the phone, like a new text message (SMS) or an incoming call. Think of it as a remote control for your Android phone via XMPP that informs you about recent events on your smartphone. Note: Newer versions of this app may be available elsewhere, which contain proprietary software.
