Making our collective jaws drop today is Tapulous, who are claiming sales approaching $1,000,000 (that's on million) dollars a month, and news that even those Apple had no conception of just how successful the iPhone app ecosystem would be.

First, Reuters reports that Tap Tap Revenge maker Tapulous, a 20-person iPhone development team, has seen 20 million installs and 600 millions games played, adding up to sales approaching $1 million a month.

Tapulous' chief executive said he expects it to ride a wave of exponential growth in mobile app commerce in the next two years, similar to that seen recently by social gaming companies like Zynga, Playfish and Playdom. Playfish was recently acquired by Electronic Arts for $275 million in cash.

Second, the Financial Times reports that even insiders weren't expecting this level of success. Says Kleiner Perkins partner Matt Murphy, manager of the then $100m iFund announced alongside the original iPhone SDK:

"We had no idea there would be 2bn downloads by October. Most people within Apple, if you had told them it would be a fifth of that by now, they would have been pretty happy."

Part of this is attributed to Steve Jobs, of course:

Even more important was Mr Jobs’ willingness to demand that AT&T and other network carriers give up control over what sorts of programmes could operate over their airwaves. He argued that the iPhone was a computer, not a phone, and that consumers expected to be able to do many things with computers. History had shown that this kind of freedom was what drove the more profitable “ecosystems” of computers – where sales of hardware were dependent on a wide variety of useable software.

So, remove the carriers, treat smartphones like real, mobile computing platforms, and everyone (mostly) benefits? Who could have imagined that?
