Create an iPhone App to control and send a command to my Arduino Mega 2560

Using Arduino Networking, Protocols, and Devices

Hi,

I designed a small line following car using IR sensors and an Arduino Mega 2560. I implemented a keypad on the car that asks the user for the time of a run and also the speed in mph. I would now like to design an iPhone app that will ask a user to enter these inputs wirelessly, instead of using the keypad that's already on the car. Is it possible and has anyone ever done this?

Best,
