Castle should do it, especially since they actually can with the 3.0 update. I bet people would buy castle escs just for this reason.
I wonder how much it would actually cost to make a program for the iphone / itouch. It would be nice because castle would only have to realease an update, not redesign a hand held programmer for new escs.
Apple is set to release the 3.0 update this summer, so I am going to leave the os alone.
I am NOT saying that castle shouldnt make the hand held programmer, they should make this in addition.
It should be called "Castle Creations iLink"
