First of all, I can control Arduino from iPhone by using Processing and TouchOSC app.

But my task is to achieve a control wirelessly "without using a PC" in between. I need to control Arduino directly by iPhone via "wifi". I should only use an Arduino, a shield, an iPhone and the wifi network. This is the task i am given.

I am really confused which way to use and which shield to buy.

I would be so glad to have your opinions.

Regards,

The WiFly Shield is basically a pcb with a Roving Networks WiFi module on it. You can configure it to set up an Access Point and connect your iPhone to the same AP.

I haven't used the WiFly Shield but I have used the Roving Networks WiFi modules and they are very flexible. They got a complete WiFi stack onboard and are pretty straightforward to use.
