Bill Dudney created a [sample iPhone Bonjour application](http://bill.dudney.net/roller/objc/resource/NetworkingTesting.zip) to demonstrate how to use Bonjour to discover and connect to two iPhones. Unfortunately, this application was made for ios2.2.1. Does anyone know how to convert this application to the new ios4? OR if someone knows of another example application that is made for ios4?
