Is it just me, or is Apple's iTunes/iOS technology really difficult to understand? I mean Apple is supposed to be the intuitive answer to Microsoft - and IBM and everyone else that ever produced an operating system, yes? What's difficult is figuring out this opaque scheme of how Apple ties content on an device like an iPad through iTunes on a PC to the Apple store and why I can't transfer apps on my wife's iPad to iTunes. My wife got an iPad 1 maybe 18 months ago (?) and over that period she has accumulated a number of apps somehow. Some she downloaded for free, I think, a few we paid for. By now she has a good deal of content on this iPad, which is currently at iOS 4.3.3. She wants to upgrade to a later release of iOS so she can use it with a work-related app that requires at least 5.x. So I logged into a PC and installed iTunes on the account I logged into. I then connected the iPad to the PC, which correctly downloaded the device drivers and the iPad popped up in iTunes. I was following instructions from an earlier post in this forum by "marilyn" who seems very knowledgeable. She said to first transfer all the apps from the iPad to the PC/iTunes. When I tried to do this, iTunes told me that it couldn't transfer 19 apps because this computer wasn't authorized and to go to Store and Authorize this computer, which I did. But subsequent attempts to transfer the apps failed with the same error and the same 19 apps it wouldn't transfer. What am I doing wrong here? Thx in advance for any help.
