iPhone 5 not recognized in iTunes

I received my new iPhone 5 via mail.  Before I activated it I upgraded my iPhone4 to iOS6 and my mac to 10.8.2 so everything would be up to date.  My iPhone5 never showed on iTunes in my device list. My iPad2 and old iPhone4 continued to show in the device list.  I have restarted my iPhone5 and Mac since activating and connected my iPhone5 to my mac desktop to see if it would complete the process.  The iPhone5 showed up in the device list as long as it was connected but disappeared when unplugged.

What should I do to get my new phone recognized by my iTunes account.
