MINO Wireless - Make cheap international calls from BlackBerry

MINO Wireless is a service not unlike Vonage, but for your BlackBerry. It allows Voice-over-IP (VOIP) calls that initiate from the internet browser of your BlackBerry. You can call over 40 countries for $0.02/minute, and you don't pay your mobile provider for the call.

You simply register at www.minowireless.com from a desktop computer, and then go to getmino.com on your BlackBerry to start using the service. You get some time for free when you register. You can add money to your account with any credit card at either the website or from your handheld directly.

From MINO:

MINO™ has developed new technology to use mobile phone's Internet (data) connection to make international calls. With MINO™ you can call from any phone to any phone worldwide. This service combines the convenience of mobile phones and the lowest rates from any country to any phone worldwide without calling local access numbers, or having to dial PIN numbers. MINO™ offers 2 cents per minute to over 40 countries worldwide!

While this isn't strictly an over-the-air download, you can use it from the BlackBerry Internet Browser.
