iTouch 2G 32GB 3.1.2 There has been much discussion on this, but no answers that work for me. I get notification of updates available, but when I try to update, I get "can't connect to itunes store". If I delete the app and re-install it, everything works fine. This is OK except for those apps (e.g.Readdle docs) which have a ;ot of my data in them. Why can I install but not update?
