Scenario: I sync my iPhone to my home macbook pro and always have. I also have a work computer, but I've only ever plugged into that to charge up. When the window comes up on that computer (a windows machine) saying that it cannot connect via itunes unless I put my PIN in on the phone, I simply *don't* do that, and all is well. It charges, and my work machine gets zero access to the innerds of the phone. Good! But: today when I plugged in I also happened to unlock the phone's screen for a sec so I could start an app. My work computer grabbed "authority" to see the phone and now is capable of browsing my photos and seeing what I have installed via iTunes. Here's where my scenario is different from others I've seen - thankfully, it did not actually SYNC, so my phone still syncs normally with the Mac. I verified. And I have since selected the "don't automatically sync" on the Windows machine. But that work laptop still can browse my phone despite my having changed my PIN afterwards. Is there any way to make my work computer LOSE the ability to browse this phone? I can't see how.
