I have found a new wrinkle that I can't deal with, which is not much of a surprise. My iPad App, will download with the apple id that is registered to my iMac and iPad, but when an update comes in for one of the applications, it uses a gmail address that was deleted over a year ago, I don't know the password or how it got on my month old iPad, except it must have been stored on the iMac. Anyway, How do I get rid of it and get it synced to the same address? nearly nutz!! 
. Hope someone has an answer. Thanks
