The iPhone, like most modern mobile devices, is based on the ARM 
processor, for which there is currently no GHC port.

However, jhc outputs portable C code which can be (cross) compiled for 
ARM. I have succeeded in building Haskell code with jhc on my desktop 
(x86 Linux), then cross-compiling the resulting C code in a scratchbox 
environment for my Nokia N810.

In short, if you can compile C code for the iPhone (cross-compiled or 
native), you can probably use jhc to turn Haskell into suitable C.

jhc is not self-hosting, and it requires gcc as a back-end, so it isn't 
suitable for running on the device.
