One of the most frequent questions of iPhone/iPad users is how to open Camera Roll on the computer you're using.
Well, you probably already noticed that you can't transfer your Camera Roll content through iTunes, which is quite annoying... So, I'll tell you how to get your Camera Roll stuff in your computer with some easy steps.
Step 1: Connect your iDevice to your Mac with the USB cable.
Step 2: When it's connected, go to Finder > Applications > Image Capture.
Step 3: After this software recognizes your iDevice, you'll be able to do whatever you want with your Camera Roll content in your computer (this includes deleting, saving on computer, etc).
Note: I'm still looking for this tutorial in a Windows version. Stay tuned.
