If someone experimented can confirm me if it's possible to use wireless serial communication between 2 xbee pro s1 : one plugged to an arduino FIO and another one plugged to an 'xbee usb explorer' connected to the iphone using a usb camera connexion kit.
It is possible to get the two XBees to communicate. The XBee on the Arduino can also communicate with the Arduino.
Whether the XBee on the other end can communicate with the phone is the only question.
Since there are no links to click in your post, you'll have to determine that yourself.
