I thought of this earlier today, also. I did another restore, but went back as a new iPad instead of restore from backup, which wiped all the apps off and deleted the email configures. I have readded one of the email accounts, and changed the "advanced" setting to delete from server when deleted from iPad, (Hope I don't live to regret this). Then I went to the app store and added only apps specific to the iPad. I had 70+ apps for my phone and had moved them all to the iPad, and I think that maybe a ghost came with one of them (Simular to your thought). So now I have 8 extra apps and so far so good, but it still flushes itself back to the home screen once in a while as you are using an app. Going into Settings>>email>> doesn't lock up now (for now), we'll see what happens. I have spent hours on this. It would be good if cheap ass Apple would include a few instructions....warnings in the box so just maybe i wouldn't have loaded something that was going to cause this much headache. Thanks again,
Also, once a month or so, I trave thru Dayton on my way to Lewiston calling on customers. Nice little town.
