This is the most advanced 2D fluids simulation application that is available for the iPhone. The iPhone is a brilliant device for this kind of application because you get instant feedback and nice interaction using the multitouch screen and inbuilt accelerometer. Drag your finger across the screen to inject new liquid and/or stir around what is already there. Tilt the device to make the liquid react to gravity.
You can load your own images (or take new ones using the camera) to use as the base texture of the fluid. You can also save out an image of the fluid whenever you fancy!
The application also has features for constant emitters, constant applied forces and collision walls that you can add/edit as you want.

Warning: The application is processor intense and will obviously run best on the newest iPhone 3G S, but will still be usable on the older 3G version. It is not recommended for the first generation of the iPhone/iPod Touch.
