When I install a binary using an XCode project generated using Unity 3 onto an iPhone running iOS 4.0, after I quite the app on the phone, the binary is not to be found on the phone. Is there a setting to change to force the binary to stay on the phone?
It will be on the iphone, you are potentially just searching in the page
XCode does not support execution of software on the device without install actually. Unity has no impact on this actually, as unity is just another iphone application
