I was developing an iPhone appliction with Xcode which I tested on my iPhone and worked properly.
Today my iPhone has been upgraded (to iOS 5, I think) and until then my device doesn't appear anymore on the devices list on XCode. It appears "iOS Device" instead of my iPhone name.
If I try now to execute my iPhone application on Xcode selecting this "iOS Device" it builds ok but it says "Xcode cannot run using the selected device".
How can I solve this ?
