I jailbroke my iPad 2 yesterday and when I try to back it up with iTunes, I keep having troubles. I connect it and back it up (after connecting it) and it change where all my apps are located and erase some of them as well. When I try to back it up again (without disconnecting it previously to this second back-up) I start getting this message: "iTunes cannot sync apps to the iPad because the apps installed on the iPad could not be determined". What can I do to fix it? Is there a way I can create a back-up with another program that don't necessary works with iTunes? One program I do have (completely paid for) is DiskAid.
