If you've ever downloaded any mobile software, chances are you've downloaded a few applications from the GetJar service-I know that I have. GetJar is saying they've had over 200 million software downloads in the past 2 years alone!

What's driving all those downloads? Free applications, of course. One application that is seeing massive growth, according to GetJar, is cellity Communicator. And why not? It's a free app and it enables a lot of functionality, such as cheap calls, free SMS, Twitter, and more!
