Good news for BlackBerry users! For the first time, there is a mobile VoIP client available that lets you use your BlackBerry to make calls over WiFi and 3G connections. A company called TringMe is the first to the table with the BlackBerry VoIP application, which is such a good idea I have to wonder why nobody has offered it before, especially given that other smartphone platforms are already offering mobile VoIP apps.
Working on BlackBerry OS 4.2 through 5.0, you can call over WiFi without using up your cellular minutes. In the absence of WiFi, you’re not left out in the cold. TringMe will place the VoIP call over your mobile Internet if there is no WiFi, or alternately, you still have the option of switching to local access numbers or callback over the cellular network.
Once you’ve installed the app, your BlackBerry browser shows “Call Using TringMe” as an option. A cool feature of TringMe is the ability to make conference calls—just select your contacts in your BlackBerry, and conference them in, without the usual third-party dial-in number or PIN.
