What is Convergence?

Convergence can be defined in many different ways. But in this case, I will define convergence in the terms of telecommunications. Convergence is when all different types of connections are used on a single device. For example, the iPhone and all the different applications that can be used on the single hand-held device. There are many other tools that can be declared to be converged; but the iPhone is the latest that goes above and beyond.
