I just updated both mine and my girlfriends ipad2's to iOS6. I noticed after the update that her apple ID was showing on MY ipad and she just noticed that MY apple ID was showing on HER ipad. Notes: We both connect to the same Airport Extreme (its up to date with latest firmware) We never download apps under each others apple IDs on the others iPad. Any ideas? This is the oddest thing i have ever encountered and its a little odd.
