I have recently had my iPhone 5 replaced at the apple store due to an antenna failure. At the time it was running iOS 7 and upon handing it over to receive the new one, iCloud was disabled and the phone was then erased and restored.
Now when I updated to Mavericks, the maps app now displays the old iPhone and the new one.
How can I get rid of the inactive iPhone? The two constantly swap around and if I want to send directions to my phone I'm forced to send it to both of them twice since every time I open the dropdown, they keep swapping around. And I realize that it's becoming a huge pain.
