No Provisioned iOS devices are available
Organizer shows the iPhone is connected with a green light.
I've tried restarting the iPhone & Xcode, and reinstalling provisioning profile, still the same dialogue box appears.
iPhone is running 4.2.1, worked fine with Xcode before the upgrade. Thinking might be something wrong with Xcode4 installation? Anything else I can try before doing a reinstall?
Any suggestions are much appreciated. Thanks in advance.
