Just finished the vb.net app for controlling my robot with an iphone. It seems it is much easier than I thought.
The connection is based on Open Sound Control. The iphone sends special messages to my laptop via wi-fi.

Great work!
I also controlled my bot with a iPhone last week, but using a different strategy.
I just used TeamViewer to remotely control my computer and use my application
