It really isn’t that simple unfortunately from both a financial and logistical stand point (being than the game on the iPhone is 3D, written in C and OpenGL).
It seems like everyone with an iPhone supports, and everyone without an iPhone disagrees.
If the one after 2.5 (if there is one) is also not on the computer, Pandemic will be a living flame war.
I understand the financial needs, and the technicalities that come with developing for iP* and the non-cross-platform-ness. Just don’t forget the people on the Web, and it’s all okay.
