I know this might sound very strange but the other day when I booted up my 2010 MBP the cursor and trackpad started going crazy. For example, I would move my finger left and the cursor would go right or up or would cause spaces to come up. Basically it would do everything except what I would tell it to do. And now today the same thing was happening to my Iphone 4s and my iPad 1. Basically whenever I touch the screen it starts to go crazy. It will open up randoms apps start typing messages in notes. However all this stuff only happens when metal is touching it. Like my auxiliary cable that is plugged into my speakers. Does anybody have any clue what this might be. I really have no clue what could be doing this. My best guess right now is that Siri is taking over my electronics. Please Help!!!!
