WHY USE BLACKBIRD:

★ NO HIDDEN COST: Once you and your friends download the application, you can use it to chat as much as you want. Send a million messages a day to your friends for free! Blackbird uses your Internet connection: 3G/EDGE or Wi-Fi when available.

★ NO INTERNATIONAL CHARGES: Just like there is no added cost to send an international email, there is no cost to send Blackbird messages internationally. Chat with your friends all over the world as long as they have Blackbird Messenger installed and avoid those pesky international SMS costs.

★ SAY NO TO PINS AND USERNAMES: Why even bother having to remember yet another PIN or username? Blackbird works with your phone number, just like SMS would, and integrates flawlessly with your existing phone address book.

★ NO NEED TO LOG IN/OUT: No more confusion about getting logged off from another computer or device. With push notifications Blackbird is ALWAYS ON and ALWAYS CONNECTED.

★ NO NEED TO ADD BUDDIES: Your Address Book is used to automatically connect you with your contacts. Your contacts who already have Blackbird will be automatically displayed.

★ OFFLINE MESSAGES: Even if you miss your push notifications or turn off your phone, Blackbird will save your messages offline until you retrieve them during the next application use.

When roaming, additional carrier data charges may apply. Please contact your carrier for details.
