I could be mistaken, but from previous articles regarding the serial port on the iPhone, this is NOT an actual RS232 port, instead it is a software emulated RS232 (serial) port, that actually does not provide low-level access to the device. Instead, it filters things in realtime, and interprets incoming/outgoing messages as needed.

"...this is NOT an actual RS232 port..."

Correct

"...it is a software emulated RS232 (serial) port..."

Incorrect. It's just TTL. You'll need to use something like a MAX232 to convert to RS232.
