Bluetooth (hopefully simple) DC Motor Control

Hello,

I'd like guidance or support on my application for a Bluetooth control of a DC motor using an Arduino (uno maybe?). The application is simple, just a simple switch that can turn the DC motor on/off. Maybe in the future it'd be nice to modulate the speed.

The only drawback, I'd like it to be applicable for iPhones. Simply, the iphone "app" would have a button to press, that will activate the motor.

THANKS!
