I realize this is a beta and there are bound to be issues, but I'm having a mildly annoying one with iCloud tab syncing. Long story short, I installed the iOS 6 beta on my iPad just to mess around with it, then reverted back to iOS 5 because I like stability. However, I am running Mountain Lion on my Air because it's pretty much final at this point and very stable. My problem is this - in the iCloud tab syncing bar in Safari, it still shows my iPad's open tabs. I can't get rid of this device. Since iPad is no longer running iOS 6, I can't simply go into it and close the tab to remove it from the list. It's just stuck there on the list and I can't find any option to unregister unused devices with iCloud or anything like that. Does anybody out there have any suggestions on how to remove this device? Would it work if I put iOS 6 BACK on the iPad, opened Safari and closed all the tabs, and then reverted back to iOS 5 again? Or would that end up in having yet another unused device on the list? Please help!
