Moving only the 201111564634_PB701SWUPDATE seems to have done the trick. Imust have misunderstood the instructions. And myle00, it did not delete anything except the icons I had on my old homepage or whatever it's called.I didn't even lose my places in my books!
Everything is there if I click on the doohickey in the middle on the bottom with all the little squares. Can you tell I know nothing about Android?
But I did not do the factory reset as I know that would remove everything.
Moving on to the next question:
I have gmail synced (I saw my emails, in any case). When I try to get into Marketplace, I get a server error. I can get online just fine, so there's nothing wrong there. I've never logged in to the marketplace, so maybe the problem is that I don't have an Android ID? What is it and how do I get one? I'm never asked for any kind of login info, so I'm confused. Oh--and I have rebooted since I set up gmail.
Even though I can't access the Marketplace, I can't sideload apps I didn't get there. And I can't find app2sd either.
