Provisioning New Device for Development Xcode
While I was sleeping, Apple completely abolished the Portal and created a new and apparently largely broken interface. It's like a kind of evil April Fools joke. Anyway, if you go to https://developer.apple.com/account/ios/device/deviceList.action there's a great big sign telling you that you must "reset your device list before adding any new devices". That sounds like it covers exactly your case. Good luck.
I also went to the iOS dev center and added the device there (not sure if I needed to do that or not).
You need to add the device there.
Steps You need to follow after adding device:
Next re-download the mobile provisioning profile again.
Go to organizer and delete the old mobile provisioning profile you had.
Double click the new mobile provisioning profile you just downloaded and see that it appears on the organizer.
Connect your device and you should see your device's name instead of iOS device.
hope this helps.
