I just saw this: http://www.tuaw.com/2011/07/19/cord-from-iphone-to-arduino-now-available/ Redpark (maker of the cable) has a Serial SDK for app dev with the cable. I assume it could be made into an external for mobile dev (?), but their licensing is for private use only. Bummer. -- Phil Davis PDS Labs Professional Software Development http://pdslabs.net
